• D. All of the above

Answer 1

Answer: (A), (B), (C)

The correct options are
A

Light is a form of energy

B

Light travels in a straight line

C

Light can travel through vacuum

The light rays from the sun travel through space to reach the earth. Hence we can say that light can propagate in the absence of a medium, that is vacuum.

We feel the heat from the rays of the sun. Thus, we can say that heat energy is transmitted through the radiations of the sun.

Also, as light forms shadow, we can say that it travels in a straight line.
