B. When its surface temperature rises on approach nearing Sun
C. When their velocity in orbit increases due to gravitational pull of Sun
D. Sunlight illuminates its tail which is always attached to its body
Check answer and explanation
Answer: When its surface temperature rises on approach nearing Sun
Explanation A comet’s tail becomes visible when it comes closer to the Sun . Heat from the Sun causes ice in the comet to vaporize (sublimation). This releases gas and dust , forming a glowing tail. The tail always points away from the Sun due to solar radiation. Comets are mostly made of ice, dust, and rocky material . Last verified on 25-04-2026
