Answer 1

The correct option is D 10

Let us arrange the given data in a table in ascending order we get,
0, 0, 0, 0, 1, 1, 2, 2, 3, 3, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9, 10, 10
Marks which are less than 4 are, 0, 0, 0, 0, 1, 1, 2, 2, 3, 3.
So, there are 10 students whose marks are less than 4.
Hence, the correct option is D.
