The list of numbers shows how many glasses of water each person drinks. (total 10 persons).

We need to find the number of glasses of water most people (out of 10) drink.

We just need to put them in order.

take 6 as the middle number

5 3 3 5 3 |6| 8 7 8 9

Similarly for the rest

3 3 3 5 5 6 7 8 8 9

So none of the answers is correct, unless there is a typo.
