The question describes the phenomenon of the greenhouse effect, where certain gases in the atmosphere trap outgoing infrared radiation (heat rays) reflected from the Earth’s surface, causing the planet to warm up. Gases like carbon dioxide, nitrous oxide, methane, and water vapour are known for this property. These gases are specifically called greenhouse gases. Therefore, option B is the correct answer.

Greenhouse gases trap outgoing infrared radiation, causing the greenhouse effect and warming the planet.

Noble gases (like Helium, Neon, Argon) are inert and do not significantly interact with radiation in this way. “Hot gas” and “Blue gas” are not scientific terms used to describe these atmospheric gases and their effect on temperature. The greenhouse effect is a natural process essential for keeping the Earth warm enough to support life, but increased concentrations of these gases due to human activities are causing enhanced global warming.
