This problem requires finding a specific letter in the English alphabet based on positional counting.
The English alphabet has 26 letters. We need to find the letter that is $15^{\text{th}}$ from the left end.
The question asks for the letter that is eighth to the right of this $15^{\text{th}}$ letter (O).
We can calculate the final position by adding 8 to the initial position (15):
Final Position = $15 + 8 = 23$
Now, we need to find the $23^{\text{rd}}$ letter in the English alphabet.
Therefore, the letter eighth to the right of the $15^{\text{th}}$ letter is W.
