Correct option is B
The correct answer is (b) Virruddha.
Viruddha, also known as contradictory middle, is a type of fallacy in Indian logic where the middle term contradicts the conclusion. In the statement "Sound is eternal because it is produced," the middle term "produced" contradicts the conclusion "eternal." This is because anything that is produced must have a beginning and an end, and therefore cannot be eternal.
