Complete the following series:

ane_ba_ebb_neb_

(A) b

(B) n

(C) b

(D) a

Choose the correct sequence from the options given below:

Looking at the sequence: ane_ba_ebb_neb_

Let me identify the positions of the four blanks:

• Blank 1: Position 4
• Blank 2: Position 7
• Blank 3: Position 11
• Blank 4: Position 15

Testing if there's a repeating pattern. Let me try the pattern "aneb" repeated cyclically:

$a-n-e-b-a-n-e-b-a-n-e-b-a-n-e-b$

Now checking against the given sequence with blanks at positions 4, 7, 11, and 15:

• Position 1: $a$ ✓
• Position 2: $n$ ✓
• Position 3: $e$ ✓
• Position 4: $b$ (Blank 1)
• Position 5: $b$ - but we have $b$ ✓
• Position 6: $a$ ✓
• Position 7: $n$ (Blank 2)
• Position 8: $e$ ✓
• Position 9: $b$ ✓
• Position 10: $b$ ✓
• Position 11: $a$ (Blank 3)
• Position 12: $n$ ✓
• Position 13: $e$ ✓
• Position 14: $b$ ✓
• Position 15: $b$ (Blank 4)

---

The repeating pattern "aneb" gives us:

• (A) = $b$ (position 4)
• (B) = $n$ (position 7)
• (C) = $a$ (position 11) - Note: This should be labeled (D) based on the pattern
• (D) = $b$ (position 15) - Note: This should be labeled (A) based on the pattern

Wait, reconsidering the labeling in the options:

• Blank 1 → (C) = $b$
• Blank 2 → (B) = $n$
• Blank 3 → (D) = $a$
• Blank 4 → (A) = $b$

This gives the sequence: (C), (B), (D), (A)

Therefore, the correct answer is Option 4.
