Correct option (c) 12
Explanation:
2 boys and 2 are to be arranged in a row so that the are not next to each other. Hence, they must sit alternatively. Let us place the boys first:
We can place these boys in 2! = 2 ways
Now, as we can see in the above arrangement, there are three places to choose from in order to place 2 *****
Number of ways we can choose 2 places out of 3 = 3C2 = 3C1 = 3
Also, the ***** can interchange their positions in 2! = 2 ways.
Hence, total number of possible arrangements = 2 × (3 × 2) = 12
