Explanation:

- Let's find the pattern by converting each letter to its position in the alphabet:

- PEARS: P(16) + E(5) + A(1) + R(18) + S(19) = 59. The relationship to 101 isn't evident.

- CAT: C(3) + A(1) + T(20) = 24. Again, no clear pattern to 49.

- Let's try a different approach. Perhaps the coding is based on a unique operation like reversing digits or incorporating a constant.

- Checking the options for MEAL:

- M(13) + E(5) + A(1) + L(12) = 31.

- Therefore, MEAL is coded as 31.

- Hence, the correct option is:

- Option 4: 31
