Explanation

Step 1: Calculate the square of 4.

4^2 = 16

Step 2: Double the square of 4.

2×16=32

Step 3: Identify the positive integers that are multiples of 3 and less than 32.

The multiples of 3 below 32 are:

3,6,9,12,15,18,21,24,27,30

Step 4: Focus on the number 18.

18 is indeed a multiple of 3.

18 is less than 32 (which is double the square of 4).

Thus, 18 satisfies both conditions, making it one of the correct answers to the problem.
