B.

Create a single S3 bucket policy that has the aws SourceVpc value and in the StingNotEquals condition to use VPC ID.

C.

Create a single S3 bucket policy that the multiple aws SourceVpce value and in the SringNotEquals condton to use vpce.

D.

Create a single S3 bucket policy that has multiple aws sourceVpce value in the StingNotEquale condition. Repeat for all the VPC endpoint IDs.
