The assertion states that a peptide bond is a planar, trans, and rigid configuration with partial double bond character. This is true. A peptide bond is formed between the carboxyl group of one amino acid and the amino group of another amino acid during protein synthesis.

The reason given states that the coplanarity of the peptide bond denotes the resonance or partial sharing of two pairs of electrons between the amide nitrogen and carboxyl oxygen. This is also true. The peptide bond has a partial double bond character due to resonance, which is a result of electron delocalization between the carbonyl carbon, the nitrogen, and the carbonyl oxygen. This delocalization or sharing of electrons creates a planar, trans configuration and contributes to the rigidity of the peptide bond.

Therefore, both the assertion and the reason are true, and the reason correctly explains the assertion. Hence, the correct answer is option 1.
