$m$-chlorobenzaldehyde on treatment with $50 \% KOH$ solution yields

In which of the following reactions,two products will be formed other than triphenylphosphine oxide $(Ph_3PO)$?

$CH_3-CH=CH-CH_2OH \xrightarrow{PCC} CH_3-CH=CH-CHO$
What is the change in hybridisation at $C-1$ in the above reaction?

Ketone reacts with $NH_2OH$ to give oxime. The reaction is as follows:
$R_2C=O + H_2N-OH \rightarrow R_2C=N-OH + H_2O$
The total number of organic products (ketoxime) formed when the simplest ketone and its next higher homologue react with $NH_2OH$,is:

Product $(C)$ of the above reaction is

Some organic compounds possess fragrance and taste. Their names are given in Column-$I$,structures in Column-$II$,and their sources in Column-$III$. Match Column-$I$ with Column-$II$ and Column-$III$.

Column-$I$ (Name)	Column-$II$ (Structure)	Column-$III$ (Source)
$(A)$ Vanillin	$(i)$ $C_6H_4(OH)CHO$ (ortho)	$(p)$ From cinnamon
$(B)$ Salicylaldehyde	$(ii)$ $C_6H_5CH=CHCHO$	$(q)$ From seeds of vanilla
$(C)$ Cinnamaldehyde	$(iii)$ $C_6H_3(OH)(OCH_3)CHO$	$(r)$ From meadow sweet
