The statement mentions that more than 95% of the people know martial art. Therefore, it can be inferred that less than 5% of people don’t know martial art, which directly supports Inference II.
Inference I suggests that 5% of people know something other than martial art. However, the statement does not imply this, as it only tells us the percentage of people who know martial art, not what the remaining 5% are doing.
Thus, only Inference II is logically supported by the given statement.
The correct answer is (a) Only inference II follows.
