C Correct answer
Explanation

The pattern involves multiplying the previous term and adding increasing powers of 2: 8×2-4=12, 12×2-4=20, 20×2-8=32. Actually, let's find the correct pattern: differences are 12-8=4, 20-12=8, 32-20=12. The differences are increasing by 4 (4, 8, 12, 16...). So next term = 32+16=48. This matches option C.
