Answer 1

The Correct Option is A

Given series: BDF, CFI, DHL, ?
Step 1: Analyze letters in each cluster
Positions of letters in the alphabet:
B (2), D (4), F (6)
C (3), F (6), I (9)
D (4), H (8), L (12)
Step 2: Observe pattern
- 1st letters: B(2), C(3), D(4) — increasing by 1
- 2nd letters: D(4), F(6), H(8) — increasing by 2
- 3rd letters: F(6), I(9), L(12) — increasing by 3
Step 3: Find next cluster
- 1st letter: D(4) + 1 = E(5)
- 2nd letter: H(8) + 2 = J(10)
- 3rd letter: L(12) + 3 = O(15)
Next cluster is EJO.
