Answer: B
The match is a-iii, b-iv, c-i, d-ii. The 7400 is a quad 2-input NAND gate, the 7402 is a quad 2-input NOR gate, and the 7408 is a quad 2-input AND gate. That leaves the quad 2-input OR gate for the 7403 in this list, which gives the code iii iv i ii.
The options that pair the 7400 with AND or the 7402 with OR misidentify the gates.
