Question

Consider the following statements:
1. The Sun at the heart of our solar system is a G-type Main sequence star.
2. Thermonuclear reactions take place in the core of the Sun.
3. Chromosphere is visible during eclipses.
Which of the statements given above are correct?

• A. 1 and 2 only
• B. 2 and 3 only
• C. 1 and 3 only
• D. 1, 2 and 3

Answer 1

The correct option is D 1, 2 and 3

A G-type main-sequence star e.g Sun , fuses hydrogen for approximately 10 billion years, until it is exhausted at the center of the star. Thermonuclear Fusion reactions are taking place continuously in the sun where two hydrogen atom combine together to form a helium atom. The chromosphere can only be seen during a complete solar eclipse. During total eclipse, the moon hides the photosphere and makes way for the reddish chromosphere to be seen.
