What blocks do Block 3 and Block 5 dominate in the flow graph for the TAC given in the passage? (Basic blocks: B1 = 100–102, B2 = 103, B3 = 104, B4 = 105, B5 = 106, B6 = 107–110, B7 = 111–112)

1. ABlock 3: 3; Block 5: 5
2. BBlock 3: 3, 4, 5, 6; Block 5: 5, 6
3. CBlock 3: 3, 7; Block 5: 5, 7
4. DBlock 3: 3, 4, 7; Block 5: 5, 6, 7
