Creating a custom Virtual Private Cloud (VPC) instead of using the Default VPC is often preferred for the purpose of having tailored configurations and improved security.

When you set up a custom VPC, you gain control over the networking environment, which includes the ability to define your own IP address range, create subnets, and configure route tables. This flexibility allows you to design an infrastructure that meets specific application requirements, network architectures, and security policies.

In terms of security, a custom VPC enables more granular control over access and isolation of resources. For example, you can implement Network Access Control Lists (ACLs) and security groups that are specifically aligned with the needs of your applications. This can help protect resources from unauthorized access, allowing you to set stringent security measures tailored to your organizational requirements.

While the other choices could touch on related concepts, they don't focus on the fundamental reasons for opting for a custom VPC. Enhancing data storage capabilities could be achieved within both custom and default VPCs; reducing costs might not have a direct correlation with the choice between a default and custom VPC; and limiting access to the public internet can be implemented in both VPC types, but a custom VPC allows for more nuanced configurations to achieve
