This question is based on the following words.
MUG TOP ACE GAS
How many letters are there between the second letter of the first word from the right and the second letter of the first word from the left as per the English alphabetical order?

The correct option is 19.

Let's break down the step-by-step logical reasoning to solve the problem:

Step 1: Identify the given words from left to right

1. First word from the left: MUG
2. Second word from the left: TOP
3. Third word from the left: ACE
4. Fourth word from the left (First word from the right): GAS

Step 2: Identify the specified letters

- First word from the right is GAS. Its second letter is A.
- First word from the left is MUG. Its second letter is U.

Step 3: Determine the positions of the letters in English alphabetical order

- The alphabetical position of A is 1.
- The alphabetical position of U is 21.

Step 4: Calculate the number of letters between A and U

To find the number of letters strictly between the 1st letter (A) and the 21st letter (U), we use the formula:

$\text{Number of letters}=(21-1)-1=19$

The letters between A and U are B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, which count to exactly 19 letters.

Hence, there are 19 letters between the second letter of the first word from the right and the second letter of the first word from the left.
