Solution

The correct option is B
Non-terminal alkynes, on oxidative cleavage yield carboxylic acids.
Lack of symmetry around the triple bond would yield a mixture of acids.
Terminal alkynes - on a similar reaction yield a carboxylic acid
and $C O_{2}$ :

So we can surmise one part - the keto acid and $C O_{2}$ as coming from:

The compound on the right has a keto group and acetaldehyde together could be attributed
retrosynthetically to:
