If GARLIC is coded as 112 then CLOCK will be coded as :​​

Given: If GARLIC is coded as 112.

Logic: Sum of opposite letters.

For, GARLIC → 112

G → 20, A → 26, R → 9, L → 15, I → 18, C →24

= 20 + 26 + 9 + 15 + 18 + 24

= 112

Similarly,

CLOCK → ?

C → 24, L → 15, O → 12, C → 24, K → 16

= 24 + 15 + 12 + 24 + 16

= 91

So, CLOCK → 91

Thus, correct option is (d).
