Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Heat and intense pressure in the early sun caused:
A
Fire in the Sun to start
B
Helium to break down into Hydrogen
C
Nuclear Fusion to start
D
Nuclear Fusion to end
Explanation: 

Detailed explanation-1: -Let’s start at the beginning of a fusion reaction. Most of the energy that is produced in the sun starts with a very simple nuclear reaction, where a hydrogen nucleus joins with another hydrogen nucleus. Eventually, a helium nucleus is formed. This reaction releases energy, and that energy heats the sun.

Detailed explanation-2: -To achieve fusion within a plasma you need to have a combination of temperature, pressure (or density) and confinement – multiplying these parameters together gives a quantity that fusion scientists call the triple product.

Detailed explanation-3: -All of these speculations were proven correct in the following decades. The primary source of solar energy, and that of similar size stars, is the fusion of hydrogen to form helium (the proton–proton chain reaction), which occurs at a solar-core temperature of 14 million kelvin.

Detailed explanation-4: -Fusion fuel – different isotopes of hydrogen – must be heated to extreme temperatures of the order of 50 million degrees Celsius, and must be kept stable under intense pressure, hence dense enough and confined for long enough to allow the nuclei to fuse.
