Solution

The correct option is A

32768


It is known that cubes of even numbers are even.

So, amongst the given numbers, 32768 and 2058 can be the cubes of an even number.

Now, 32768 = (2 × 2 × 2 × 2 × 2)3

2058= 2 × 3 × (7)3

It can be seen that 2058 is not a perfect cube.

Thus, 32768 is the cube of an even number.
