The question refers to a reaction sequence, but the actual reaction scheme/image is missing from the prompt. Without the structures/reagents leading to Product A and Product B, the number of oxygen atoms in the products cannot be derived from chemistry alone.

So:

1. Given information available: only the statement

   “Consider the given chemical reaction sequence: Total sum of oxygen atoms in Product A and Product B are ___”

2. Missing essential data: the actual chemical reaction sequence (substrate, reagents, intermediates/products).
3. Therefore, a step-by-step chemical solution is not possible from the provided text alone.

Since you also asked me to compare with the stored correct answer, the only thing I can say is:

• The stored correct answer is 14.
• But I cannot independently verify it without the missing reaction scheme.

Please upload or paste the reaction sequence image, and I can then solve it properly step-by-step.
