The total of the angles must be 180 degrees, so andle Q must measure 180-(21+37)=122 degrees. If B were true, this would need to be less than 90, so that's false. If C were true, one would need to be 90 degrees, so this is false. If D were true, two angles would need to be equal, so this is false. So the answer must be A.
