Explanation:

- The code for each word seems to be calculated based on the position of the letters in the alphabet.

- CAB: C=3, A=1, B=2. Sum = 3 + 1 + 2 = 6.

- BED: B=2, E=5, D=4. Sum = 2 + 5 + 4 = 11. However, BED is coded as 40.

- It looks like there might be an extra multiplicative or operations step involved we didn’t initially consider.

- Let's apply hypothetical logic to HAD.

- HAD: H=8, A=1, D=4. Sum = 8 + 1 + 4 = 13.

- Using a multiplier similar to BED; assume 4*10 for BED approx. Hence, 13*4 = 52 for HAD.

- ? Option: 2 - 52 is the correct choice for HAD.
