A natural number is abundant if its proper divisors (not including itself) add up to more than the number. (For example: 24 is abundant because the divisors of 24 are 1, 2, 3, 4, 6, and 12, 24 and 1 + 2 + 3 + 4 + 6 + 12 = 28 > 24) . How many divisors does the smallest abundant odd number has?

1) 18
2) 12
3) 16
4) 8
