Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In the death of a large mass star gravitational collapse is so complete that no energy or matter can escape. This is called a ____
A
Neutron Star
B
Black Hole
C
Black Dwarf
D
Supernova
Explanation: 

Detailed explanation-1: -black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. A black hole can be formed by the death of a massive star.

Detailed explanation-2: -At some point, the gravity field compresses the stellar remnant into a “black hole.” The name comes from the fact that even light cannot escape the pull of this intense gravity field if it passes within the distance from the black hole known as the “event horizon.”

Detailed explanation-3: -A supernova is the colossal explosion of a star. Scientists have identified several types of supernova. One type, called a “core-collapse” supernova, occurs in the last stage in the life of massive stars that are at least eight times larger than our Sun.

Detailed explanation-4: -Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.)

Detailed explanation-5: -What kinds of stars end up as black holes? They are the natural consequence of the evolution of massive stars. Neutron stars have an upper mass limit of 2 to 3 solar masses. A collapsed object of greater mass will continue to collapse indefinitely, forming a black hole.
