Solution

The correct option is A
The number ending with 4.

The perfect squares like 64, 144, 324, have the roots 8, 12, and 18 respectively. The unit place digit decides the ending digit of a square, like the product of 4 with itself gives 16 i.e. the ending digit of a perfect square contains 6 as its ending digit.
