The molecular geometry of the nitrogen atom in the peptide bond that links the two histidine residues in His-His is Trigonal planar (D).

Here's why:

1. In a peptide bond, the nitrogen atom is bonded to two other atoms: the carbon atom in the carbonyl group of one amino acid and the hydrogen atom.

2. The nitrogen atom also has a lone pair of electrons.

3. The geometry of a molecule is determined by the number of electron groups (which include bonding pairs of electrons and lone pairs) around the central atom.

4. In the case of the nitrogen atom in a peptide bond, there are three electron groups (two bonding pairs and one lone pair).

5. According to VSEPR theory (Valence Shell Electron Pair Repulsion theory), three electron groups will arrange themselves as far apart as possible to minimize repulsion. This results in a trigonal planar geometry.

So, the correct answer is D. Trigonal planar.
