Correct answer: (A) Fallacy of irrelevant reason

Explanation

The argument commits the fallacy of an irrelevant, inconclusive reason.

It infers that sound is impermanent from its being invisible.

Invisibility belongs to permanent things as well, such as space.

A mark shared by both permanent and impermanent things cannot prove impermanence.

In Nyaya such a straying, inconclusive reason is a hetvabhasa of irrelevant reason.
