C. Upgrade to EC2
Explanation :
Option A is INCORRECT. LightSail Backup is an invalid option.
Option B is INCORRECT. LightSail Copy is an invalid option.
Option C is CORRECT. “Upgrade to EC2” is the feature that allows customers to “create a copy of the LightSail instance in EC2”.
To get started, you need to export your Lightsail instance manual snapshot. You’ll then use the Upgrade to EC2 wizard to create an instance in EC2.
Customers who are comfortable with EC2 can then use the EC2 creation wizard or API to create a new EC2 instance as they would from an existing EC2 AMI.
Option D is INCORRECT. A LightSail-EC2 snapshot is an invalid option.
