Correct Option: C. 24/7 availability for customers Explanation of Why Option C is Correct: E-commerce refers to the buying and selling of goods and services over the internet. One of the most significant advantages of e-commerce compared to traditional retailing is its 24/7 availability. This means that customers can shop at any time of the day or night, regardless of their location.

1. Convenience for Customers: Customers can browse products, compare prices, and make purchases whenever it suits them. This flexibility is particularly beneficial for those with busy schedules or those living in different time zones. For example, a customer can shop at midnight without worrying about store hours.
2. Global Reach: E-commerce platforms can cater to a global audience, allowing businesses to reach customers who may not be able to visit a physical store. This expands the market significantly and can lead to increased sales.
3. Increased Sales Opportunities: With 24/7 availability, businesses can capitalize on impulse buying and last-minute purchases. For instance, a customer might decide to buy a gift late at night, which they would not be able to do if they had to visit a physical store.

Why the Other Options Are Wrong or Weaker: A. Limited geographical reach: This option is incorrect because e-commerce actually has a broader geographical reach compared to traditional retailing. While traditional stores are limited to their physical locations, e-commerce can serve customers from anywhere in the world, provided they have internet access. This global reach is a significant advantage for businesses looking to expand their customer base. B. Higher operational costs: This option is also incorrect. E-commerce typically has lower operational costs compared to traditional retailing. Traditional stores incur expenses such as rent, utilities, and staffing for physical locations. In contrast, e-commerce businesses can operate with fewer overhead costs, as they do not require a physical storefront. While there are costs associated with website maintenance, digital marketing, and shipping, these are often lower than the costs of running a brick-and-mortar store. D. Requirement for physical storefronts: This option is incorrect because e-commerce does not require a physical storefront at all. In fact, one of the defining features of e-commerce is that it allows businesses to operate entirely online. This eliminates the need for physical space, which can be a significant barrier to entry for many traditional retailers. Summary of Key Points:

• E-commerce offers 24/7 availability, allowing customers to shop at their convenience, which is a major advantage over traditional retailing.
• Global reach is a significant benefit of e-commerce, enabling businesses to access a wider customer base.
• Lower operational costs are associated with e-commerce compared to traditional retail, as there is no need for physical storefronts.
• E-commerce eliminates the requirement for physical locations, allowing businesses to operate solely online.

This understanding of e-commerce advantages is crucial for anyone studying commerce, as it highlights the transformative impact of technology on retailing.
