the core's extreme temperature and density are just right for the nuclear fusion of hydrogen to helium through the proton-proton chain.Energy is made through the process of nuclear fusion. This is when two hydrogen nuclei join to make helium. This occurs in the sun's core where there is very high pressure and temperature.
Nuclear fusion of hydrogen to form helium occurs naturally in the sun and other stars. It takes place only at extremely high temperatures. That’s because a great deal of energy is needed to overcome the force of repulsion between the positively charged nuclei. The sun’s energy comes from fusion in its core, shown in the Figure below. In the core, temperatures reach millions of degrees Kelvin.

Nothing is underlined in your sentence, but the sentence sounds like it is set in the present.
B. present
The answer would be C.
Since this isn't a flashback, first person, or doesn't lead to anything stressful.
It uses a lot of different words to add on the the terror of the "Death swamp," such as ooze, desperate, hopeless, or even viciously.
Cognates are words from different languages that look similar and mean the same thing. These words are usually derived from and share the same etymological origin, which is an advantage if you're looking forward to learning a new language. For example, several words in other languages such as French and Spanish have similar appearances and meanings in English, with a few even having the same spelling.
