Solution
Option 1 -> Statement (A) about innocence is not explicitly mentioned in the passage, only simplicity and cooperation are stated.
Option 2 -> Statement (B) is directly supported ("co-operation I had from the simple men and women") and statement (C) is explicitly stated ("their music, is the expression of their thoughts, feelings, hopes and aspirations").
Option 3 -> While (C) is correct, statement (D) contradicts the passage which describes their music as "free from artificial sophistication or inhibition, which is an unavoidable feature of any urban society."
Option 4 -> Both statements are incorrect - (A) is not mentioned and (D) contradicts the passage.
Hence, Option 2: (B) and (C) only -> The passage explicitly describes the village folk as "simple men and women" who provided cooperation to the author, and clearly states their music expresses "their thoughts, feelings, hopes and aspirations." Statement (D) is incorrect as their music is characterized as distinctly non-urban, being "free from any kind of artificial sophistication." -> correct
