Your organization has deployed their e-commerce application on Oracle Container Engine for Kubernetes (OKE) and they are using the Oracle Cloud Infrastructure Registry (OCIR) service as their Docker image repository. They have deployed the OKE cluster using the 'custom create' option, and their Virtual Cloud Network (VCN) has three public subnets with associated Route Tables, Security Lists, and Internet Gateway. However, their application containers are failing to deploy. On investigation, they discover that the images are not being pulled from the designated OCIR repository, even though the YAML configuration has the correct path to the images. What is a valid concern here that needs to be further investigated?

• A.Identity and Access Management (IAM) credentials need to be added for each user that deploys applications to the OKE cluster.
• B.Security List rule for TCP port 22 needs to be added to connect to the OCIR service.
• C.OKE cluster needs to have a secret with the credentials of their OCIR repository and use that secret in the Kubernetes deployment manifest.
• D.VCN hosting the OKE cluster worker nodes needs to have a NAT gateway to access OCIR repositories.
