Answer:
After its main Sequence existence a medium sized star like our sun becomes a red giant.
Explanation:
A red giant star is a large reddish star whose mass ranges from about 0.3 to 8 times the mass of our sun. Red giants are stars that are already at an advanced stage of their “life”. .
At this stage, due to the fusion of hydrogen into helium in the outer layers, these same layers eventually expand into a red giant. At this stage the star has already left the so-called main sequence.
A red giant star has a diameter of a few dozen, or even hundreds of times the diameter of our sun. However, the limits of this star are not well defined due to the low density of the outer layers.
The surface temperature of a red giant is relatively low, usually no more than 5,000 K.
Later, the red giant star eventually expels its outer layers, forming what we call the planetary nebula. Meanwhile the red giant's core remains cohesive by its own force of gravity. This nucleus that remains of the red giant becomes a white dwarf, a small but very dense star.
Examples of red giant stars: Aldebaran and Arcturus.

The one which best describe a steppe is a grassland with few trees Option(b) is correct. Steppe dry land with xerophilous vegetation found for the most part in locales of outrageous temperature reach and loess soil.
The Russian name for such woods is taiga, as steppe is the Russian word for meadows; and it is advantageous to utilize these terms to portray the two zones of vegetation that put forth limited lines on human existence.
Steppes are essential fields on dry territories, which are not appropriate for the foundation of trees in sloping districts, lower regions, and marshes Steppes are exceptionally assorted and mosaic-like territories described by perpetual graminoids of Bromus.
The Western Steppe was moderately immaculate by people until the seventeenth hundred years. Prior, the region was occupied by roaming clans that involved the land as field for homegrown steers and for hunting. The primary rural settlements were created by the Romans in the western piece of the steppe along waterway valleys of the Dniester.
Therefore Option(b) is correct.
