[A]. only found between proline residues
[B]. usually cis unless proline is the next amino acid
[C]. usually trans unless proline is the next amino acid
[D]. is planar because of steric hinderance

But the peptide bond is planar. This is what I know. Please explain.

Its planar but not because of steric hinderance.

Yes, the peptide bond is a planner but not of a stearic hindrance. And peptide bond is also a non-polar btw alfa amino group of amino acid and alpha-carbonyl group of another amino acid.

Right option would be C because peptides bonds are planner, trans and also exhibited resonance properties.
