Three-letter groups skipping one – UGC NET Question

The groups are three consecutive letters and each new group starts two letters after the start of the previous one. The starting letters A, C, E and G correspond to positions 1, 3, 5 and 7, all increasing by 2. The next starting letter must therefore be position 9, which is I, and the group formed is IJK. This satisfies both the skip of one letter between starting positions and the three letter consecutive structure.

Option A:
Option A, HIJ, begins at H, which is position 8 and only one step after G. This ignores the observed pattern of moving the starting position by two positions. Although HIJ is a valid consecutive block, it does not respect the skip rule that defines the series.

Option B:
Option B, JKL, starts at J, which is position 10 and three positions after G. This overshoots the required increment and creates a larger gap than any previous step. Because the series maintains a consistent plus two movement, JKL cannot be correct.

Option C:
Option C, KLM, is even further ahead and increases the offset between starting letters even more. It would represent a later term in a continuation, not the immediate next group. As there is no jump of four positions in the given pattern, KLM does not fit the series.

Option D:
Option D is correct because I is exactly two positions after G, and IJK is a three letter consecutive group. It preserves the pattern of skipping one letter between the starting points and keeps the internal order unchanged. For these reasons, IJK is the logical continuation of the letter group series.
