Correct Option: B. Mary Explanation of the Correct Answer In the context of Christian Religious Studies, particularly when discussing the New Testament, Martha is a well-known figure who appears in the Gospels. She is primarily recognized for her relationship with her brother Lazarus and her sister Mary. The correct answer to the question about Martha's sister is Mary.

1. Biblical Context: Martha and Mary are mentioned in the Gospels of Luke (10:38-42) and John (11:1-44). In Luke, we see Martha welcoming Jesus into their home, while Mary sits at Jesus' feet, listening to His teachings. This passage highlights the different roles and personalities of the two sisters. In John, both sisters are present when Jesus raises their brother Lazarus from the dead, further emphasizing their familial bond.
2. Significance of Mary: Mary, the sister of Martha, is often associated with devotion and contemplation, contrasting with Martha's active service. This dynamic is significant in Christian teachings, illustrating the balance between action (service) and contemplation (listening to Jesus).
3. Cultural and Theological Implications: The relationship between Martha and Mary has been the subject of theological reflection, particularly regarding the roles of women in the church and the importance of both service and spiritual growth. This makes Mary a pivotal character in understanding the teachings of Jesus and the early Christian community.

Explanation of Why Other Options Are Incorrect

• A. Elizabeth: Elizabeth is a different biblical figure, known as the mother of John the Baptist. She is not related to Martha and does not appear in the same narrative context. Therefore, this option is incorrect.
• C. Joanna: Joanna is mentioned in the Gospel of Luke as one of the women who supported Jesus' ministry and was present at His resurrection. However, she is not related to Martha and does not share the same familial connection. Thus, this option is also incorrect.
• D. Susanna: Susanna is another woman mentioned in the Gospels who supported Jesus and His disciples. Like Joanna, she is not related to Martha and does not appear in the same stories. Therefore, this option is incorrect as well.
