Correct Option: B. a holder of a first university degree Detailed Explanation: To qualify for absorption into the administration cadre of the civil service in Nigeria, the primary requirement is that an applicant must hold at least a first university degree. This requirement is established to ensure that individuals entering the civil service possess a foundational level of education that equips them with critical thinking, analytical skills, and a basic understanding of governance and public administration.

1. Educational Requirement:
2. The civil service in Nigeria is structured to include various cadres, and the administration cadre is one of the key areas where educated individuals are needed to manage public affairs effectively. A first university degree signifies that the applicant has undergone a rigorous academic process, which is essential for understanding the complexities of public service.
3. Importance of a Degree:
4. Holding a degree is not just about having a piece of paper; it reflects a level of commitment to education and personal development. It also indicates that the individual has been trained in critical areas such as communication, research, and problem-solving, which are vital for effective governance.
5. Legal Framework:
6. The Nigerian civil service is governed by various laws and regulations that outline the qualifications necessary for different positions. The requirement for a first degree is often stipulated in these regulations, making it a formal prerequisite for entry into the administration cadre.

Why the Other Options are Wrong or Weaker:

• Option A: Knowledgeable in civil service rules:
• While knowledge of civil service rules is beneficial and may be required for certain roles within the civil service, it is not a formal qualification for entry into the administration cadre. An applicant can learn these rules on the job or through training after being employed. Therefore, this option does not meet the primary qualification criteria.
• Option C: Specifically trained in public administration:
• Although training in public administration can enhance an applicant's suitability for a role in the civil service, it is not a mandatory requirement for entry. Many individuals with degrees in other fields can also perform effectively in administrative roles. Thus, this option is too narrow and does not encompass the broader educational qualifications accepted for entry.
• Option D: A senior civil servant:
• This option is misleading because it implies that only those already within the civil service can qualify for the administration cadre. In reality, the civil service seeks to bring in fresh talent and perspectives, and new applicants are encouraged to apply regardless of their previous employment status. Therefore, this option does not align with the entry requirements.

Revision Summary:

• To qualify for the administration cadre of the civil service in Nigeria, an applicant must hold a first university degree.
• A degree ensures that candidates have the necessary educational background for effective public service.
• Knowledge of civil service rules, specific training in public administration, or being a senior civil servant are not formal entry requirements.
• The civil service aims to attract a diverse range of educated individuals to enhance governance and public administration.
