Answers
C.
Add a schema patch that implements Magento\Framework\setup\Patch\PatchRevertabieinterface and drops the table in the revert function.
Suggested answer: C

Explanation:

According to the Declarative Schema Overview guide for Magento 2 developers, declarative schema is a new feature that allows developers to declare the final desired state of the database and has the system adjust to it automatically, without performing redundant operations. However, declarative schema does not support uninstalling modules or reverting changes. To remove a table when a module is disabled, the developer needs to add a schema patch that implements Magento\Framework\setup\Patch\PatchRevertabieinterface and drops the table in the revert function. The revert function will be executed when the module is disabled using bin/magento module:disable command. Verified
