Stars more than about 3 times the mass of the sun are likely to wind up as neutron stars. Stars more than about 10 times the mass of the sun will probably end up as black holes.

Obviously I can't see "the following groups", but the answer must be "white dwarfs".
The five medium stars are the Sun, Alpha Centauri A, Sirius A, Vega, and Capella. These stars have masses and luminosities greater than average stars like our Sun, but are not as massive or luminous as giant stars.
Helium is converted to carbon in the final stage of fusion in stars like the Sun, which are considered to be medium-sized stars. This happens during the triple-alpha process where three helium nuclei combine to form a carbon nucleus.
The final stage of supergiant stars is a supernova explosion. When these massive stars exhaust their nuclear fuel, they can no longer support their own gravity, leading to a catastrophic collapse of the core. This collapse results in a rebound effect that expels the outer layers, creating a bright and powerful explosion. Depending on the mass of the original star, the remnant can become a neutron star or a black hole.
White dwarf stars.
Stars with masses greater than 100 times that of the Sun would burn their fuel so rapidly that they would not have enough time to reach the main sequence before exhausting it and ending their lives in violent supernova explosions. Therefore, there are no stars with masses much greater than 100 solar masses currently observable in the universe.
A white dwarf is the last stage of stellar evolution for stars with masses similar to our Sun. A black hole, on the other hand, is the last stage of stellar evolution for stars having very large masses, many times greater than that of the Sun. Consequently, very few stars end up as black holes. Additionally, black holes have an escape velocity greater than the speed of light, while a white dwarf's escape velocity is less than the speed of light.

In the interior of certain massive stars.

They are attracted to one another by gravity, which is not affected by electrical charge. Gravity is an attractive force that occurs between all objects with mass. You don't have positive and negative masses that attract and repel. The greater the mass, the greater the attraction. Second, the stars do not all have the same mass. The masses of stars vary considerably.
For HIGH mass stars- 1. the hydrogen in the core burns until only helium is left. 2. Then the core contracts, while the outer layers expand. 3. It expands into the red-giant stage and 4. then to the super-giant stage. 5. It will finally die in a supernova explosion, 6. leaving behind a white dwarf (if its final mass is less than 1.4 solar masses), a neutron star (if the final mass is between 1.4 and 3 solar masses) or a black hole (if the final mass is more than 3 times that of the Sun).

The masses of the two stars.

This is too broad. All stars have different masses.
