For $C_6H_5CHO$,which of the following is incorrect?

The products of acid hydrolysis of $P$ and $Q$ can be distinguished by:
$P = H_2C=C(CH_3)(OCOCH_3)$
$Q = H_3C-CH=CH(OCOCH_3)$

In the following reactions,$P, Q, R$,and $S$ are the major products.
The correct statement$(s)$ about $P, Q, R$,and $S$ is(are):
$(A)$ Both $P$ and $Q$ have asymmetric carbon$(s)$.
$(B)$ Both $Q$ and $R$ have asymmetric carbon$(s)$.
$(C)$ Both $P$ and $R$ have asymmetric carbon$(s)$.
$(D)$ $P$ has asymmetric carbon$(s)$,$S$ does not have any asymmetric carbon.

The product formed when hydroxylamine $(NH_2OH)$ condenses with a carbonyl compound is called:

Consider the above reaction sequence and identify the product $B$.
