Answer:
<u>Lower latitudes to higher latitudes i.e low pressure to high pressure.</u>
Explanation:
- As the pressure gradient is a force that is derived from the lower latitude to the upper latitudes in the form of pressure systems and the winds belts that arise from ITCZ zone thus there is an upwelling of warm and hot air from this region and goes upwards to the polar regions and in between from a convective cycle.
- There is a characteristic of this zone in the form of a vigorous thunderstorm over large bodies of the ocean. All this heating is derived due to the sun's rays fall directly over the equator.
- ITCZ being the doldrum zone or zone of calms sets the surface air to fly pass creating a frontal situation of the hot and cold air mass to interact and create eddies in the oceans.

<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.
