Step 2:Observe pattern:

• Frequent repetition of patterns like ab, aba, abb
• Suggests alternating and structured placement of a and b

Step 3:Try option (B) ababb: Fill sequentially: This forms a consistent and smooth pattern of alternating letters.
Step 4:Other options break the pattern or create irregular sequences.}
Step 5:Final Answer:

Concept: Look for repeating patterns or symmetry in the letter sequence. Step 1:Write the pattern with blanks:
Step 2:Observe repeating structure: Notice that:

• ``NB'' repeats at the end
• Pattern suggests repetition of letters in alternating form

Step 3:Try option (C)} OWOW: This forms a consistent alternating and repeating structure.
Step 4:Other options do not maintain symmetry or repetition properly.}
Step 5:Final Answer:
