A company is running services in a VPC with a CIDR block of 10.5.0.0/22. End users report that they no longer can provision new resources because some of the subnets in the VPC have run out of IP addresses.

Add 10.5.2.0/23 as a second CIDR block to the VPC. Create a new subnet with a new CIDR block, and provision new resources in the new subnet.
Add 10.5.4.0/21 as a second CIDR block to the VPC. Assign a second network from this CIDR block to the existing subnets that have run out of IP addresses.
Add 10.5.4.0/22 as a second CIDR block to the VPC. Assign a second network from this CIDR block to the existing subnets that have run out of IP addresses.
Add 10.5.4.0/22 as a second CIDR block to the VPC. Create a new subnet with a new CIDR block, and provision new resources in the new subnet.
