Answer:

a. Increases tremendously in luminosity

Explanation:

  • The helium flash is a thermal nuclear fusion with large quantities of helium gas into carbon. During the red giant phase, the sun is predicted to have a flash 1.2 billion after it leaves the main sequence and this helium fusion cannot be produced by the low mass stars.
  • The sun in this stage will burn out or run out of its fuel and eventually will lead to gravitational collapse.  The star being to shrink in size and core starts to collapse.

A CT air mass is <br><br>hot and wet <br>cold and dry <br>hot and dry <br>cold and wet ​
Arturiano [62]

The correct answer is - hot and dry.

The CT air masses are air masses that originate from deep inside the land masses in the tropical regions of the Earth. The ''C'' actually stands for continental, thus indicating the formation of the air mass over a land mass, while the ''T'' stands for tropical, thus indicating the tropical region of where the land mass over which this air mass forms.

Because these air masses form over land in the tropics, they are hot and dry. The hot and dry characteristics come from the bigger heating of the land masses, as well as the lack of water vapor over the land masses.
