P shows the knee joint. The knee joint is a hinge joint, which allows movement along one axis only, to flex or to extend.Q shows a joint where our neck joins the head. It is a pivotal joint. It allows us to bend our head forward and backward and turn the head to our right or left.Now, let’s check the given options and find the incorrect one regarding these two joints:A. Joint P allows movement in one direction only. ----- Correct. Joint P is a hinge joint, which allows movement along one axis only, to flex or to extend.B. Joint Q allows movement in many planes. ----- Correct. Joint Q allows us to bend our head forward and backward and turn the head to our right or left.C. Knee bones have two P joints. ----- Incorrect. Knee bones have just one hinge joint.D. Joint Q acts like a pivot and allows the circular motion of the part around it. ----- Correct. We can move our head around in circular motion at the neck joint.Hence, Option C is the right answer.

Rithvik Chandra from Greenwood High School, Bangalore

even if it looks like shoulder joint, it is incorrect, because shoulder joint has only one hinge joint not two, same for knee. and they said select the INCORRECT option, hence it is option C. And if you dont beleive me ask your science/biology teacher, they will say the same thing.
