8. Choose the odd one out: L, N, P, S, T

Explanation: To identify the odd one out, we analyze the position of each letter in the English alphabet:

• L is the 12th letter of the alphabet (even position).
• N is the 14th letter (even position).
• P is the 16th letter (even position).
• S is the 19th letter (odd position).
• T is the 20th letter (even position).

From this analysis, S stands out because it is the only letter with an odd position (19th), while all the other letters (L, N, P, and T) have even positions (12th, 14th, 16th, and 20th, respectively).

Thus, the odd one out is S, as it is the only letter in the group with an odd-numbered position in the alphabet.
