When the average is 5. Then there exists some sample points all around the value of 5 !
There should be some sample points <=5, some >=5, some < 5, some > 5.
There may or may not be any sample points = 5 as mean is a theoretical value.
I think the answer should be (D).
@Arjun, sir, people from the community, have I gone wrong somewhere ?
