Given numbers are 4, 6, and 8.

Let the fourth proportional be x.

To find the fourth proportional, we use the formula:

First : Second = Third : Fourth

So, we have:

4 : 6 = 8 : x

Cross-multiplying, we get:

4x = 6 x 8

4x = 48

x = 48/4

x = 12

Therefore, the fourth proportional to 4, 6, 8 is 12.

Hence, option (a) is the correct answer.
