Question

Ordinarily the barrier to rotation about a carbon-carbon double bond is quite high but in compound P, the double bond between the two rings was observed by NMR to have a rotational barrier of only about 20 cal/mol, showing that it has lot of single bond character.

A
The double bond has a partial triple bond character due to resonance
