Number of hyper conjugation resonance structures of ${\mathrm{BH}}_3\cdot \mathrm{CO}=x$

Number of hyper conjugation resonance structure of ${\mathrm{BH}}_3\cdot {\mathrm{PF}}_3=y$
Choose the correct relationship.

In reality, the option B building contains only 5 H. Only five possible hyper conjugating structures exist.

Therefore, the answer of x=y=3 is the proper relationship.
