Answer and explanation

Correct answer: Empty set

The condition requires an integer strictly greater than 0 and strictly less than 1. There is no integer between 0 and 1; numbers such as 0.5 are not integers. Consequently, no integer satisfies the condition, so A contains no elements and is the empty set ∅. Hence option A is correct.
