Answer 1

Answer:

Option D

Step-by-step explanation:

No students scored above 90 on both exams ( Incorrect as there are three dots more than 90 marks).

One student scored exactly 60 on both exams ( Incorrect as the dot is not exactly on 60, it seems slightly less than 60)

All the students scored between 60 and 100 on both exams ( Incorrect, there are couple of students which scored less than 60 also )

More than half the students scored between 70 and 80 on both exams (Correct, as the major cluster of dots is in this region)
