C Correct answer
Explanation

Subtract remainder from both numbers: 245-5 = 240 and 1029-5 = 1024. Find GCD of 240 and 1024. 240 = 16 × 15, 1024 = 16 × 64. GCD is 16. Verification: 240/16 = 15 remainder 0, 1024/16 = 64 remainder 0. 12 doesn't divide 1024, 14 doesn't divide 240 evenly, 20 is not the GCD.
