If the second half of the English alphabet is reversed then which letter will be 4th to the right of 20th letter from the right?

U K E F

K

The answer is K. The second half of the English alphabet is reversed, so the 20th letter from the right is G. The 4th letter to the right of G is K. The other options are incorrect: U is the 21st letter from the right. E is the 5th letter from the right. F is the 16th letter from the right.
