PASS : QBTT :: FAIL : ?

GJBM
GBJM
MBJG
MJBG

The correct answer is A. GJBM.

In the sequence PASS : QBTT, the first letter of each word is moved three places forward in the alphabet to get the corresponding letter in the second word. So, P becomes Q, A becomes B, S becomes T, and so on.

Following this rule, the first

letter of FAIL becomes G, the second letter becomes J, the third letter becomes B, and so on. This gives us the word GJBM.

The other options are incorrect because they do not follow the rule of moving the letters three places forward in the alphabet.
