I have been asked this question by my school principal while I was bunking the class.

I would like to ask this question from Heat Sink for Power Transistor-2 topic in portion Power Amplifier of Analog Circuits

Answer 1

The correct choice is (c) Device to transfer heat from device to the sink

The best I can explain: A heat spreader conducts heat between a heat source and a heat sink. Most commonly, a block of material with high thermal conductivity is used as a heat spreader.
