CSI and standard General Conditions define the architect/engineer’s submittal review purpose as confirming that submittals conform to the design intent shown and specified in the contract documents — not to approve means, methods, or to revise design.

The A/E’s review checks:

General compliance of the submittal with design intent.

Coordination among trades.

Any deviations that require clarification or change approval.

It is not for:

Designing or redesigning (Option A),

Supervising construction procedures (Option C), or

Evaluating formal substitution requests (Option D) — substitutions are separately submitted for approval under Division 01 procedures.

Therefore, the A/E reviews submittals to monitor design conformance, making Option B correct.
