In a certain code language, if ANGLE is coded as 1147125, then how is DOING coded in
that language?

Correct option is C

Based on the pattern where letters are replaced by their alphabetical positions (A=1, B=2...) and then potentially manipulated; ANGLE (1, 14, 7, 12, 5) becomes 1147125, so DOING (4, 15, 9, 14, 7) becomes 4159147 by direct substitution, matching option C.
Identify the Pattern: Look at ANGLE (A=1, N=14, G=7, L=12, E=5) coded as 1147125. It seems to be a direct concatenation of their positional values.
Apply to DOING:
D = 4
O = 15
I = 9
N = 14
G = 7
Combine: Concatenating these gives 4159147, which matches option (C).
