Answer 2

Answer:

B) Only I and III

Step-by-step explanation:

I) Sqrt of 1296 = 36

III) Sqrt of 20736 = 144

The product of numbers in (II) is 7776 which is not a perfect square.

To check if a number is a perfect square the units place in the number should be 0, 1, 4, 5, 6 or 9. But still there are exceptions as 7776.
