Word series BAT CAT DAT EAT – UGC NET Question

In this series, the last two letters “AT” remain fixed, while only the first letter changes in alphabetical order. The first letters progress as B, C, D, E, so the next first letter must be F. Attaching the constant suffix “AT” to F gives FAT. Hence FAT is the only word that continues the simple first-letter progression.

Option A:
Option A, GAT, uses the correct suffix but jumps from E to G, skipping F. The rule shows every adjacent letter in order without omissions. Because it violates the immediate alphabetical succession, GAT cannot be the next term.

Option B:
Option B, HAT, goes even further, skipping both F and G. This disregards the clear pattern of moving to the very next letter at each step. Therefore HAT does not fit the orderly progression established in the series.

Option C:
Option C, EAT, simply repeats the last given term instead of advancing the pattern. The series requires a new word with the next first letter, not a repetition. As there is no indication of cycling, EAT cannot be the correct answer.

Option D:
Option D is correct because it keeps “AT” unchanged and moves from E to F exactly once. This agrees perfectly with the observed behaviour of changing only the first letter in strict alphabetical order. Therefore FAT is the logical continuation of the series.
