Question

hot spot 1 point click on the amine group.

Explanation:

The amine group in an amino acid (like the one shown, which appears to be alanine in its zwitterionic form) is the part containing nitrogen. Here, the group $\ce{H3N+}$ (or the neutral $\ce{-NH2}$ group in non - ionized form, but in this zwitterion it's protonated as $\ce{H3N+}$) is the amine group. To identify it, we look for the nitrogen - containing group attached to the central carbon (the alpha - carbon) of the amino acid. In this structure, the $\ce{H3N+}$ group is the amine group (protonated amine, also called ammonium group in this ionized state, but still the amine - derived group in the amino acid).

Answer:

The amine group is the $\boldsymbol{\ce{H3N+}}$ (or the group containing the nitrogen atom bonded to the central carbon, with three hydrogens attached in this protonated form) part of the structure. To click on it, you would interact with the $\ce{H3N+}$ group in the given molecular diagram.
