Identify the number which does not satisfy: Sum of digits is a divisor of the number.
39
For each option, compute the sum of digits and check whether it divides the number exactly.
21: digit sum = 2 + 1 = 3; 21 ÷ 3 = 7 (exact). ✓
30: digit sum = 3 + 0 = 3; 30 ÷ 3 = 10 (exact). ✓
36: digit sum = 3 + 6 = 9; 36 ÷ 9 = 4 (exact). ✓
39: digit sum = 3 + 9 = 12; 39 ÷ 12 = 3.25 (not exact). ✗
So the number that does not satisfy the condition is 39.
Hence, the correct answer is 39.
