The steps of the conversion is as follows
Step A: PCC oxidation of primary alcohol to corresponding
aldehyde
Step H: Addition of cyano group to the aldehyde. Please note that
aldehyde is more reactive than ketone,
Step G: Hydrolysis of cyano group to the corresponding carboxylic
acid group
Mechanism of hydrolysis of cyano group is also given below
Step 1: protonation of cyano group nitrogen
Step 2: water molecule addition to the nitrile carbon
Step 3: Addition of second water molecule
Step 4: Elimination of ammonia and formation of carboxylic acid
group

I thought about a hydrolysis first to get to an amide. Then we
would also need D in order to add the right alkyl part, but cannot
figure the whole sequence.
