The answer here is D, and it's kind of obvious. But you probably already knew the answer and are just doing this for piece of mind.

Explanation: Just the fact that we don't know whether or not there even is extraterrestrial life rules out every other answer, without even needing to go in depth.

(Okay, I read your question completely wrong, it's asking for which one of these has been solved isn't it?)

This is tough because all of these other than D have been figured out. Go with the methane atmosphere then.

Svetach [21]

Water has a characteristically high specific heat, making it an important vector (or mechanism) for redistributing heat around the globe.

Specific heat can be defined as the quantity of heat required to raise the temperature of one gram of a substance by one degree Celsius. The units of specific heat are usually calories or joules per gram per degree Celsius.

The specific heat of water is 1 calorie (or 4.186 joules) per gram per degree Celsius. The incoming radiation from the sun is responsible for warming up the Earth. Water in particular, has a high heat capacity at 4.18 J/g*C, which indicates that more heat is needed to warm a gram of water. This is the reason that throughout a warm summer day, the water in the ocean does not experience a significant change.

I am Lyosha [343]

Since prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.

<h3>What are prokaryotic cells?</h3>

Prokaryotic cells are cells that are characterized by the absence of a nucleus or any other membrane-bound organelles.

On the other hand, eukaryotic cells have the presence of a membrane-bound nucleus that stores their genetic material.

Another important feature of prokaryotic cells is that they are haploid in nature i.e. they do not have chromosomes that occur in homologous pairs and have just one chromosome.

Therefore, it can be said that because prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.
