Heya..! Here is your answer.
========================================
(a) For the handles and bristles of toothbrush we can not choose same type of plastics because bristles are used to clean our teeth and gum. So it must be a type of thermoplastic that is nylon but handles of toothbrush must be strong and tough so that it can give some grip and resist our efforts on it. So it should a type of thermosetting plastic.
=========================================
(b) The handle and bristles of a tooth brush should not be made of the same material. As handle require strength and stiffness so it
should be made from plastic. Where as bristles are soft and elastic so they should be made from nylon.
Hope it helps ^o^

Answer:
The handle and bristles of a tooth brush should be made of different materials. The material which is used for making toothbrush handle should be hard and flexible; because the handle has to withstand lot of stress and has to reach every corner of mouth. The material which is used for making bristles should be soft, flexible yet durable; because the bristles should not damage the tooth or gum but should last longer.
