(B) To find the number of pairs of letters in the word $ANSWER$ that have the same number of letters between them as in the English alphabet,we check both forward and backward directions:$1$. Word: $A, N, S, W, E, R$$2$. Forward direction:- $A$ to $N$: $1$ letter between ($N$ is at position $2$,$A$ is at $1$,$2-1-1 = 0$ letters between). In English,$A$ and $N$ have $12$ letters between them.- $A$ to $S$: $A(1), N(2), S(3)$. $2$ letters between. In English,$A$ and $S$ have $17$ letters between them.- $N$ to $S$: $N(14), S(19)$. $4$ letters between $(O, P, Q, R)$. In the word,there is $1$ letter $(S)$.- $R$ to $E$: $R(18), E(5)$. Backward: $E, F, G, H, I, J, K, L, M, N, O, P, Q, R$. There are $12$ letters between $E$ and $R$ in the alphabet. In the word $ANSWER$,the letters between $E$ and $R$ are none. Wait,let's check alphabetical order:- $A(1), N(14), S(19), W(23), E(5), R(18)$.- Pair $(A, E)$: $A(1)$ and $E(5)$. Letters between in word: $N, S, W$ ($3$ letters). Letters between in alphabet: $B, C, D$ ($3$ letters). This is a match.- Pair $(N, R)$: $N(14)$ and $R(18)$. Letters between in word: $S, W, E$ ($3$ letters). Letters between in alphabet: $O, P, Q$ ($3$ letters). This is a match.There are $2$ such pairs.

How many pairs of letters are there in the word $ANSWER$,each of which has as many letters between them in the word as there are in the English language?
