Question

Which best describes nuclear fission?

A. the burning of carbon
B. the decay of radioactive isotopes
C. the splitting apart of atomic nuclei
D. the release of a tiny packet of energy

Answer 1

It's C.

Step-by-step explanation:

Firstly, the burning of carbon produces C02, a greenhouse gas. As nuclear fission does not produce carbon dioxide, it is not A. The decay of radioactive isotopes is not fission, or spliting into 2 parts.

As fission means to split, it is C.
