The correct answer is
B

Letter Series Pattern

The series provided is L, J, H, F, D, ?

Finding the Pattern

Convert letters to their alphabetical positions:

  • L = 12
  • J = 10
  • H = 8
  • F = 6
  • D = 4

The sequence of positions is 12, 10, 8, 6, 4. The pattern is subtracting 2 from the previous position.

Determining the Next Letter

To find the next letter, subtract 2 from the position of D (which is 4):

Next Position = $4 - 2 = 2$

The 2nd letter in the alphabet is B.
