Four letter evenly spaced jump series – UGC NET Question

In this series, every group consists of four letters with the same fixed distance between consecutive letters. AEIM shows a regular pattern of positions, and BFJN, CGKO and DHLP repeat that structure with their own starting points. From one term to the next, each column increases by one letter in the alphabet. Advancing every letter of DHLP by one yields EIMQ, which keeps the constant internal spacing and extends the vertical sequences, so EIMQ is the correct next term.

Option A:
Option A, EGMR, alters the internal differences between letters and no longer keeps the equal steps that AEIM, BFJN, CGKO and DHLP share. It also does not come directly from adding one to each letter of DHLP. Because the spacing and transformation are both off, EGMR cannot be correct.

Option B:
Option B, EIFQ, begins with E and I like the true answer but changes the remaining letters so that the final gaps inside the group differ from the earlier pattern. The positions of F and Q do not fit the repeated structure. Hence EIFQ breaks the consistent internal rule of the series.

Option C:
Option C, FJNQ, moves the starting letter too far ahead and modifies multiple columns in a way that does not match the simple one step shift from DHLP. Its letters are not aligned properly with the previous vertical sequences. Therefore FJNQ does not continue the series correctly.

Option D:
Option D is correct because EIMQ is exactly one alphabetical step ahead of DHLP in each position and keeps the same spacing between successive letters. It fits neatly after the earlier groups, respecting both the constant internal step and the column wise progression. This makes EIMQ the only option that satisfies the observed pattern.
