I say A

1. if 12 are added could divide evenly by 8...
works for 4, 12, 20...mults of 4 but not mults of 8. add 4 to each of these and u get a # divisible by 8...

2.doesn't work alone, and statement 1 shows us that has to be a mult of 4 but not 8, so we dont need this.

It is A.

Statement 1 says that (x+12) = 8k where x is no of students in a dance class and k is an integer. So if 4 added, x+4 has to be divided by 8 because (x+12) = (x+4+8) and it 8 is taken out, (x+4) remain and it is divisible by 8. so St. 1 is Suff.

Statement 2 says that x is not divisible by 8 means x could be even or odd. Even if it is even, x is not divisible by 8. If it is odd, no question. Hence insuff.
