Solution

The correct option is A
$1$

A triangle cannot have more than one $90 °$ or right angle, because by the angle sum property of the triangle, we know that, sum of all the three angles of a triangle is equal to $180 °$ . If two angles are of $90 °$ , then the third angle has to be zero, which is not possible.
