Answer and explanation

Correct answer: {1}

Natural numbers less than 2 are considered from the counting sequence 1, 2, 3, and so on. Among them, only 1 is less than 2, and 1 is odd. Therefore, the set contains exactly one element, written as A = {1}. It is a singleton set, not an empty set, because one number satisfies the stated condition.
