Option (C)

Explanation:

The color of a star plays a significant role in identifying its temperature and this colors observed are directly dependent on their surface temperature. Stars has the capacity to emit lights of different wavelength. These lights usually ranges from reddish to bluish in color. A star that appears to be red in color indicates a cool star, whereas a star that appears to be blue in color indicates a hot burning star.

The more cooler it is, the more reddish it appears and the more hotter it is, the more bluish it becomes.

Thus, the correct answer is option (C) i. e a blue star is more hotter.
