Answer: The answer is (d) 96.

Step-by-step explanation:

Let the first term of the G.P. be 'a' and the common ratio be 'r'.

Given that the 2nd term is 'ar' and the 3rd term is 'ar^2'.

Also, given that the 5th term is 8 times the 2nd term:

ar^4 = 8(ar)

r^3 = 8

r = 2

Substituting r = 2, in the equation for the 3rd term:

ar^2 = 12

a(2)^2 = 12

a = 3

So, the first five terms of the GP are:

a, ar, ar^2, ar^3, ar^4

= 3, 6, 12, 24, 48

Now, to find the 6th term:

ar^5 = 96

3(2)^5 = 96

6th term = 96

Therefore, the answer is (d) 96.

I hope this helps!
