Which of the following is evidence religious tension in South Asia a. civil war in Sri Lanka b. Soviet invasion of Afghanistan c. Pakistani government attack in East Pakistan d. British colonization of India

The events provided can all be connected to broader issues in South Asia, but the one that is most directly linked to religious tension is:

a. civil war in Sri Lanka

The civil war in Sri Lanka, which lasted from 1983 to 2009, was significantly influenced by ethnic and religious divides, primarily between the Sinhalese Buddhist majority and the Tamil Hindu minority. This conflict involved not just ethnic but also religious tensions, making it a clear example of how such divisions can lead to civil strife in the region.

While the other options also involve conflict and issues in South Asia, they are not as explicitly tied to religious tension as the civil war in Sri Lanka.
