Exact Extracts from Salesforce Subscription Management and CPQ Implementation Guides:

“The InitiateRenewal invocable action enables users or flows to create a renewal quote or renewal order based on existing active assets or contracts.”

“Admins can expose this flow action through a screen flow and add it as a quick action on Account, Contract, or Asset record pages for one-click renewal initiation.”

“This declarative approach eliminates the need for custom triggers or processes.”

Step-by-Step Reasoning:

Requirement: Allow sales reps to trigger renewals directly from a record page with minimal clicks.

Correct Solution: Use InitiateRenewal invocable action within a screen flow.

Deployment: Add the flow as a Quick Action on the Account or Contract Lightning page.

Why B is Correct: It uses native Revenue Cloud functionality for renewals, no code required.

Why Others Are Incorrect:

A: Apex trigger is custom and bypasses standard renewal processes.

C: Checkbox + Process Builder is outdated and not integrated with Renewal APIs.
