(D) To find the pairs,we count the letters in the word $HORIZONTAL$ and compare their positions with the English alphabet:$H(8), O(15), R(18), I(9), Z(26), O(15), N(14), T(20), A(1), L(12)$.Checking forward and backward:$1$. $H$ to $L$: $H(8), I(9), J(10), K(11), L(12)$. There are $3$ letters between them in the word $(O, R, I, Z, O, N, T, A)$ - No.$2$. $H$ to $N$: $H(8)$ to $N(14)$ has $5$ letters $(I, J, K, L, M)$ in the alphabet. In the word,$H$ to $N$ has $O, R, I, Z, O$ ($5$ letters). This is a pair.$3$. $R$ to $N$: $R(18)$ to $N(14)$ has $3$ letters $(O, P, Q)$ in the alphabet. In the word,$R$ to $N$ has $I, Z, O$ ($3$ letters). This is a pair.$4$. $O$ to $N$: $O(15)$ to $N(14)$ has $0$ letters in the alphabet. In the word,$O$ and $N$ are adjacent. This is a pair.$5$. $R$ to $O$: $R(18)$ to $O(15)$ has $2$ letters $(P, Q)$ in the alphabet. In the word,$R$ to $O$ has $I, Z$ ($2$ letters). This is a pair.Thus,there are four pairs: $(H, N), (R, N), (O, N), (R, O)$.Since there are four pairs,the correct option is 'More than three'.

How many such pairs of letters are there in the word $HORIZONTAL$,each of which has as many letters between them in the word as they have between them in the English alphabet?
