Find the missing number / letters / word from the given alternative: AYBZC, DWEXF, GUHVI, JSKTL, ?

The correct answer is A. MQORN.

The sequence is a simple substitution cipher, with each letter being replaced by the letter three places after it in the alphabet. So, A becomes M, B becomes N, C becomes O, and so on.

The first few letters of the sequence are:

• AYBZC
• DWEXF
• GUHVI
• JSKTL

The next letter in the sequence is MQORN.

This is because M is three places after A, N is three places after B, O is three places after C, and so on.

Therefore, the correct answer is A. MQORN.
