Question

which one among the following four values of squares ends with its last digit six

Answer 1

I request you to ask complete questions.
Your question is missing the options of four values.

But I can tell you that....
6ⁿ
for any value of n, the last digit of the resulting number is always 6.
So 6² results in 36, where last digit is 6.

Also, 4² results in 16.
Last digit is 6.
