How many figures show right angles made by them?

A2

B1

C3

D0

answer should be B because in figure one i.e triangle has 4 right angles inside the figure and we cannot say that they have not included the inside ones because the clock they are saying that clock hands are not right angles but the clock hands are inside figure so basically we can count the inside angles so answer should be B
