<u>Answer:</u> The correct answer is Option b.
<u>Explanation:</u>
Nuclear fusion reaction is defined as the reaction in which lighter nuclei combine together to form a single heavier nuclei.
Another name for helium nuclei is alpha particle.
For the given options:
- <u>Option a:</u> The CNO cycle
This cycle is named as carbon-nitrogen-oxygen cycle. In this cycle, carbon absorbs a proton to form nitrogen which further absorbs a photon to form oxygen. Thus, helium particles are not getting fused in this process.
- <u>Option b:</u> The triple alpha process
This process is a set of nuclear reaction in which 3 alpha or helium nuclei combine together to form carbon nucleus.
The equation representing the fusion process follows:

- <u>Option c:</u> Photo dissociation
This is defined as the process in which a chemical compound is broken down by photons. Thus, helium particles are not getting fused in this process.
- <u>Option d:</u> The proton-proton chain
This process is a set of nuclear fusion reactions by which stars convert hydrogen nucleus to helium nucleus. The chemical reactions for this process are:

Here, fusion of protons takes place.
Hence, the correct answer is Option b.
<span>The answer is definitely C. The
Midwestern United States is an example of a vernacular region. Indeed, the
Midwestern has been generally acquainted and explained by both travelers and
habitants quite mistakenly (most of them characterize the region as some little
town and so on). Moreover, the vernacular element can also be found by paying
attention to the emotional charges these people display while talking about the
Midwestern (most of them knows everybody in town and they have still ongoing
things with some of the city residents). </span>
Human expansion, Hunting and increased poaching.

Water pollution which is a major problem in urban areas have some of the causes such as dumping refuse to the water bodies, discharging of industrial wastes to the water bodies and it is a major problem to the people who rely on this water supply because they can contact disease from the water when they drink it.
<h3 /><h3>What is water pollution?</h3>
Water pollution can be described as the act of dropping any substance that can contaminate the natural state of water into the water bodies.
It should be noted that this one of the problem in the urban cities and this as a result of the discharging of waste from the industries.
