F 4 A % T 9 µ Z M 3 N # L & E 2 X C 7 G D * O 5 R ∞ H 1 J $ @ K 8 B

If all the numbers are removed, then which element is 5th from the right end?

The correct option is J.

Let's find the solution step-by-step:
1. Write down the original sequence:
F 4 A % T 9 µ Z M 3 N # L & E 2 X C 7 G D * O 5 R ∞ H 1 J $ @ K 8 B

2. Identify and remove all the numbers from the sequence:
The numbers in the sequence are: 4, 9, 3, 2, 7, 5, 1, and 8.
Removing these numbers gives us the new sequence:
F A % T µ Z M N # L & E X C G D * O R ∞ H J $ @ K B

3. Count the elements from the right end of the new sequence:
- 1st element from the right: B
- 2nd element from the right: K
- 3rd element from the right: @
- 4th element from the right: $
- 5th element from the right: J

Therefore, the 5th element from the right end when all numbers are removed is J.
