Short answer

The product followed as:

Step-by-step solution

Claisen ester condensation

It is a reaction in which 2 equivalent of the same ester condense to form beta keto ester by the abstraction of a proton from one ester and this leads to the addition of another molecule of ester.

Reaction of compound A

As per the given product, the abstraction of proton occurs and the abstraction is very easy due to the presence of most acidic hydrogen due to two carbonyl and then another molecule of ester attack on the anionic part and form beta keto ester as shown:

Reaction of compound B

In the given product the abstraction of the proton occurs ethoxy anion and the abstraction is very easy due to the presence of most acidic hydrogen due to two carbonyl and then another molecule of ester attack on the anionic part and form beta keto ester followed by the removal of the ethoxy group next to the carbonyl and addition of another ester molecule occur as shown:
