Correct option is D
Given: In a certain code language, ‘NANDA’ is coded as '14-1-14-4-1’ and ‘GOPAL’ is coded as ‘7-15-16-1-12’.

Logic: Direct coding is given.
For, NANDA → 14-1-14-4-1
N → 14, A → 1, N → 14, D → 4, A → 1
For, GOPAL → 7-15-16-1-12
G → 7, O → 15, P → 16, A → 1, L → 12
Similarly,
BISWAS → ?
B → 2, I → 9, S → 19, W → 23, A → 1, S → 19
So, BISWAS is coded as 2-9-19-23-1-19.
Thus, correct option is (d).
