Solution

The correct option is C
Suresh is incorrect, Ramesh is correct.

There are four quadrants made by two perpendicular lines,which intersect each other, as is clear from the above picture. Now, in each quadrant, the angle made by the two lines is 90°. Therefore, total number of right angles = 4.
