Options

Answer 1

Answer:

24

Step-by-step explanation:

just to make work easier

you square the last figure of every option

that is the square of 1 .......from 61 is still one

the square of 4 ........from 24 is 16

so i have gotten an even number already

so i believe the rest will give an odd number ........ there for the answer is 24

as simple as that
