We have to determine whether the number 3(a + b) + c divisible by 3. Since 3(a + b) is a multiple of 3, it is divisible by 3. So, the question boils down to whether c is divisible by 3.

Since Statement 2 states that c is divisible by 3, Option B is the correct answer.

The correct answer: B

Hope this helps!
