When matter is converted in a nuclear reaction:

a. a small amount of energy is absorbed
b. a small amount of energy is released
c. a large amount of energy is released

The correct answer is C) A large amount of energy is released.

Explanation-

There are two types of nuclear reaction, which are called fusion and fission.

Nuclear fusion is the type of nuclear reaction in which two light unstable nuclei fuse together to form a heavy stable nucleus with the release of high amount of energy.

Example- Hydrogen bomb that is the energy formation in stars.

Nuclear fission is the types of nuclear reaction in which a heavy unstable nucleus splits into two light stable nuclei with the release of high amount of energy.

Example- Decay of Uranium- 235 into Krypton- 92 and Barium- 141.

Thus, correct option is C)  A large amount of energy is released.

answer; i believe the correct answer is (sporophyte);

i am going to guess that it is co2.
