Correct answer: A
Concept: In this letter-to-number coding scheme, each letter's position in the alphabet (A = 1, B = 2, ... , Z = 26) is increased by a fixed constant, and the resulting numbers for every letter of the word are written one after another, with no separator, to form the code.
Application — first confirm the shift using the given code for DRLAL:
D is the 4th letter of the alphabet; 4 + 2 = 6
R is the 18th letter; 18 + 2 = 20
L is the 12th letter; 12 + 2 = 14
A is the 1st letter; 1 + 2 = 3
L is the 12th letter; 12 + 2 = 14
Writing these results in order — 6, 20, 14, 3, 14 — gives 62014314, which matches the given code exactly, confirming that a fixed +2 shift is applied to each letter's alphabet position before concatenation.
Now apply the same rule to CAMEL:
C is the 3rd letter; 3 + 2 = 5
A is the 1st letter; 1 + 2 = 3
M is the 13th letter; 13 + 2 = 15
E is the 5th letter; 5 + 2 = 7
L is the 12th letter; 12 + 2 = 14
Concatenating these results in order — 5, 3, 15, 7, 14 — gives 5315714.
Cross-check: reversing the rule — subtracting 2 from each block of the derived code (5, 3, 15, 7, 14) — recovers 3, 1, 13, 5, 12, which are exactly the alphabet positions of C, A, M, E, L, confirming the forward derivation is self-consistent.
