In order to determine the reason for most of the United States' humanitarian support to countries in Africa at the end of the 20th century and the start of the 21st century, we can eliminate the options that are not relevant or do not match the timeframe.

Option A, "combating communism," is not directly related to humanitarian support to African countries. While the United States did provide support to certain countries as part of its broader Cold War strategy, this answer does not specifically address humanitarian efforts in Africa.

Option D, "diplomatic efforts to end apartheid," is also not the primary reason for the United States' humanitarian support to African countries during this time period. While the United States did support ending apartheid in South Africa, it was not the main focus of its humanitarian efforts in Africa as a whole.

This leaves us with options B and C: "medicine to fight against AIDS" and "stopping the spread of malaria." Both of these health issues were major concerns in Africa, and the United States did provide significant humanitarian support in combating them.

To determine which is the primary reason, we can assess the impact and scale of the United States' efforts. At the end of the 20th century and the start of the 21st century, AIDS was a significant global health crisis, particularly in sub-Saharan Africa. The United States launched initiatives such as the President's Emergency Plan for AIDS Relief (PEPFAR) in 2003, which provided substantial funding for treatment, prevention, and support programs in African countries affected by HIV/AIDS. This indicates that option B, "medicine to fight against AIDS," was a major driving force behind the United States' humanitarian support in Africa during this time period.
