(c) The sun
(d) Electric bulb

Answer 1

Answer:

The Firefly is the cold source of light

Answer 2

Which of the following is a cold source of light?

Explanation:

• Fireflies produce a chemical reaction inside their bodies that allows them to light up.
• Unlike a light bulb, which produces a lot of heat in addition to light, a firefly's light is "cold light" without a lot of energy being lost as heat.
• Firefly (Jugnu) emits short bursts of light.
• So, (a) Firefly (Jugnu) is correct.
