Vidwat Amal from Podar International School , Anand

A, B, D are correct....incorrect is C. Because forearm is the length of the arm between elbow joint and wrist joint but the cubit is length from tip of elbow to the tip of the middle finger. so forearm length is smaller than the cubit. So answer is option C

In the solutions , it says that a colored plastic bottle is a opaque material... However , it is actually a translucent material...:( Maybe since the coloured bottle is translucent , a faint shadow will be seen.. So , here it says that no shadow will be seen at all , which I think is false.. Hope this helps:)
