If FRANCE is coded as 654321 and GERMANY is coded as 9158437, then how is YEMEN coded?

Mapping from given codes: FRANCE → 654321 gives F=6, R=5, A=4, N=3, C=2, E=1. GERMANY → 9158437 gives G=9, E=1, R=5, M=8, A=4, N=3 (wait, but A=4 and N=3 already match!), Y=7. So Y=7, E=1, M=8, E=1, N=3. But wait the code 9158437 has 7 digits for 7 letters: G-E-R-M-A-N-Y → 9-1-5-8-4-3-7. So Y=7, E=1, M=8, N=3. YEMEN = Y-E-M-E-N = 7-1-8-1-3? That gives 71813, which is option (d). Re-check carefully: Y=7, E=1, M=8, E=1, N=3 → 71813. Hmm, option (d) is 71813. But option (c) 71913 has a 9. Re-examining: per the assignment, YEMEN = 71813 = option (d). Answer is (d) 71813.
