Step 1: Let's look at the pattern in the given sequence:
- ``fgg" is followed by ``gff," indicating the letters ``f" and ``g" alternate between the positions.
- After ``gff," the next sequence is ``f," which suggests the pattern continues with alternating ``f" and ``g" letters.
Step 2: If we complete the sequence with ``fggf" in the gaps, we maintain the alternating pattern between ``f" and ``g," creating the series:
\[ fggf \, gff \, f \, gfg \, fgfo. \] This fits perfectly with the given pattern. Thus, the correct answer is option (A) fggf.
