which reactions are the reverse of one another?\ncondensation and addition\naddition and elimination\nelimina…

Brief Explanations:

In organic chemistry, addition reactions involve adding atoms or groups to a molecule, while elimination reactions remove atoms or groups from a molecule. They are reverse - type reactions. Condensation involves the combination of molecules with the loss of a small molecule like water, and it's not the reverse of addition or elimination. Substitution replaces one atom or group with another and is not the reverse of addition.

Answer:

B. addition and elimination
