Universal Containers is adding drone delivery to service offerings.

The correct action is to validate the inbound change set in Production before the deployment window. Salesforce states that an inbound change set can be validated without deploying changes, and validation shows the same success or failure messages that would occur during an actual deployment.

This helps the app builder confirm whether Apex tests, dependencies, and deployment requirements will pass while the developer is away.

Why not others:

A is wrong because removing Apex classes would remove required code.

B is wrong because deployment validation is done from the inbound change set in the target org.

C is not the standard change-set validation process.
