In a certain code, BALD is denoted by 1,2,4,12 and FISH is denoted by 9,6,8,19. KEEN must be denoted by:

a) 5, 12, 12, 14
a) 5, 11, 11, 15
a) 5, 11, 14, 5

In a certain code, BALD is denoted by 1,2,4,12 and FISH is denoted by 9,6,8,19. KEEN must be denoted by:

a) 5, 12, 12, 14
b) 5, 11, 11, 15
c) 5, 11, 14, 5
d) 11, 5, 5, 14
e) None

Not a valid GMAT problem.
Anyone prepping for the GMAT should feel free to ignore this problem.
That said, the code seems to function as follows:

1st number = where the word's SECOND letter appears the alphabet.
2nd number = where the word's FIRST letter appears in the alphabet.
3rd number = where the word's FOURTH letter appears in the alphabet.
4th number = where the word's THIRD letter appears in the alphabet.

BALD:
1st number = where the word's second letter ("A") appears in the alphabet = 1.
2nd number = where the word's first letter ("B") appears in the alphabet = 2.
3rd number = where the word's fourth letter ("D") appears in the alphabet = 4.
4th number = where the word's third letter ("L") appears in the alphabet = 12.
Resulting code:
1, 2, 4, 12.

FISH:
1st number = where the word's second letter ("I") appears in the alphabet = 9.
2nd number = where the word's first letter ("F") appears in the alphabet = 6.
3rd number = where the word's fourth letter ("H") appears in the alphabet = 8.
4th number = where the word's third letter ("S") appears in the alphabet = 19.
Resulting code:
9, 6, 8, 19.

KEEN:
1st number = where the word's second letter ("E") appears in the alphabet = 5.
2nd number = where the word's first letter ("K") appears in the alphabet = 11.
3rd number = where the word's fourth letter ("N") appears in the alphabet = 14.
4th number = where the word's third letter ("E") appears in the alphabet = 5.
Resulting code:
5, 11, 14, 5.

The correct answer is C.

If # = a letter's number in the English alphabet (A = 1, B = 2, ..., Z = 26), ONE INTERPRETATION of our code is

abcd = (#b)(#a)(#d)(#c)

so KEEN = (#E)(#K)(#N)(#E) = (5)(11)(14)(5)

As Guru notes above, though, this wouldn't be on the GMAT, since there could be more than one interpretation of the code. (This is also why you don't see "What's the next number in the sequence?" type problems on the GMAT.)
