14. N

Step 3: Find the positions of the letter "e".
The letter "e" appears at the 2nd, 8th positions in the word.

Step 4: Quantify the letters.
L: 1, P: 1, A: 2, E: 2, D: 1, U: 1, S: 2, I: 2, N: 1, Q: 1

Step 5: Examine the letters we enumerated.
The target letter was "e" and there we found 2 total.
