Answer:
Option (3), (4), (5) and (6) are the correct statements
Step-by-step explanation:
A star that cannot undergo nuclear reaction is considered to be a dying star.
The characteristics of a dying star are as follow-
(a) A dying star undergoes an explosion during its last stage.
(b) A dying star becomes dimmer and stops glowing at the end because it cannot undergo nuclear reaction and its temperature eventually decreases, as a result of which its luminosity decreases.
(c) A star that has a very large solar mass (about ten times the mass of the sun) can turn into a black hole as it gets collapse or gets exploded.
(d) During the time of dying of a star, the star gets expanded and the size increases and the explosion takes place it gets collapsed.
Thus, the correct statements are options (3), (4), (5) and (6).
