Detailed explanation-1: -Supergiants develop when massive main-sequence stars run out of hydrogen in their cores, at which point they start to expand, just like lower-mass stars. Unlike lower-mass stars, however, they begin to fuse helium in the core smoothly and not long after exhausting their hydrogen.
Detailed explanation-2: -When the hydrogen in the centre of a star runs out, the star begins to use hydrogen further out from its core. This causes to star to grow. Its radius can reach up to 400 times its original size.
Detailed explanation-3: -Answer and Explanation: The mass of the star determines if a star becomes a white dwarf, a neutron star, or a black hole. This is because its mass determines how much gravitational energy there is and thus what degree of compression it can undergo.
