Let as assign position values to each of the people standing in the queue.
Henry is fourth is the line, and hence the position/rank of Henry = 4

Given that there are n people ahead of Eleanor, where n>4. So, Eleanor cannot be in any position between 1 and 4 (Henry's position)
Since n people ahead of Eleanor, the position/rank of Eleanor = n+1

In order to find the number of people between Henry and Eleanor, we simply need to subtract the position of Henry from Eleanor, i.e. (n+1) - 4 = n - 3
Hence, the correct option is answer choice C. n - 3

Could you please check the option B? Is it (n-b) or something else?

Say there are 8 people in front of Elenor and Henry is in position 4, the no.of people between Eleanor and Henry is coming out to be 4 or (n-4).

E _ _ _ _ H _ _ _

Another example with n=10 people in front of Eleanor.

E _ _ _ _ _ _ H _ _ _

The no of people between Eleanor and Henry is 6=(n-4).

Is there a typo in the options or am I missing something?

Cheers!
