Answer: Execute a command through a management service to apply the patch on all instances.
Option D is the correct answer. AWS Systems Manager Run Command allows you to remotely and securely manage the configuration of your managed instances, including running scripts and commands. This is the most efficient and flexible way to apply custom patches to a large number of EC2 instances quickly. The other options are less suitable; for example, AWS Lambda is not designed to directly manage EC2 instances, and Patch Manager is more oriented towards managing patches released by AWS or major software vendors rather than third-party software.
