Question

During the transformation of a massive star ultimately into a black hole, which of the following sequence is correct?

• A. Red giant stage $\to$ Supernova stage $\to$ White dwarf stage
• B. White dwarf stage $\to$ Red giant stage $\to$ Supernova stage
• C. White dwarf stage $\to$ Supernova stage $\to$ Red giant stage
• D. Red giant stage $\to$ White dwarf stage $\to$ Supernova stage

Answer 1

The correct option is D Red giant stage $\to$ White dwarf stage $\to$ Supernova stage

When a star dies, the star enters a black hole. There is a loss of hydrogen and the star forms a red giant star which burns highly. This star then transforms to a white dwarf stage which cools and ceases to burn. Th e next stage is the supernova which results in an explosion of the star burning and shining very brightly.

Thus, the correct answer is option D.
