Correct answer: D

Explanation

The correct answer is D because it properly outlines the steps required to share the transit gateway from the Connectivity account and create the necessary attachment in the Production account. The other options incorrectly reference VPC subnets instead of the transit gateway or do not follow the correct sequence of accepting resources and creating attachments.
