Correct answer: A
Concept
In an alphabet-position coding rule, replace each letter with its position A = 1, B = 2, ..., Z = 26. For this scheme, add those positions and then add the number of letters in the word.
Application
First verify the rule with the given example, then apply the same rule to CHAIR.
TABLE gives T + A + B + L + E = 20 + 1 + 2 + 12 + 5 = 40.
TABLE has 5 letters, so its code is 40 + 5 = 45, which reproduces the given code.
CHAIR gives C + H + A + I + R = 3 + 8 + 1 + 9 + 18 = 39.
CHAIR also has 5 letters, so its code is 39 + 5 = 44.
Cross-check
Subtracting the five-letter count from 44 gives 39, exactly the alphabet-position sum for CHAIR.
Therefore, CHAIR is coded as 44.
