Auranium atom absorbs a neutron and transforms into a zirconium atom, a tellurium atom, and three neutrons. this is an example of a. fusion b. fission c. a chemical reaction d. both fission and fusion

The correct answer is B.

Nuclear fission is a reaction in which a heavy atom splits into two or more atoms whereas in fusion, two lighter atoms combine to form a different atom.

In nuclear reactions, a change in atom's nucleus is involved which causes it to change into other element. Whereas in chemical reactions, rearrangement of electrons is involved and there is no change in the nucleus of the atom. Therefore, the given reaction is nuclear fission.
