Answer: Greenhouse gases arise naturally, and are part of the make-up of our atmosphere. Earth is sometimes called the “Goldilocks” planet – it’s not too hot, not too cold, and the conditions are just right to allow life, including us, to flourish. Part of what makes Earth so amenable is the naturally-arising greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average. But in the last century or so, humans have been interfering with the energy balance of the planet, mainly through the burning of fossil fuels that give off additional carbon dioxide into the air. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth, causing temperatures to rise.

Answer:
The correct answer will be option-D
Explanation:
RNA or ribonucleic acid is the nucleic acid which was formed in the primordial time. The RNA molecule acts as an enzyme called ribozyme and also acts as the genetic material of a few viruses.
The RNA is composed of nucleotide monomer where each nucleotide is made of a ribose sugar, a phosphate group and the nitrogenous base adenine, uracil, cytosine and guanine.
Thus, option-D is the correct answer.
