Show answer and explanation

Correct answer: (D) Some of Ravi's friends are hardworking and kind.

Explanation

The passage says that almost all of Ravi's friends are hardworking and kind, so at least some of them are. "Almost all" rules out that all of them are (A). Nothing is said about people who are not Ravi's friends (B), and only some of his friends are said to lack interest in sports, so (C) does not follow.
