B. Access keys "Access keys are long-term credentials for an IAM user or the AWS account root user. You can use access keys to sign programmatic requests to the AWS CLI or AWS API (directly or using the AWS SDK)." https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html

B. Access keys allow programmatic access to AWS resources for use from the AWS CLI or the AWS API. Access keys are a pair of access key ID and secret access key that are used to securely sign API requests to AWS services. These keys are necessary to authenticate API requests made using AWS SDKs, the AWS Command Line Interface (CLI), or directly using the APIs. The access keys can be created and managed through the AWS Management Console or through the AWS Identity and Access Management (IAM) API.

The credential that allows programmatic access to AWS resources for use from the AWS CLI or the AWS API is access keys. Therefore, option B is the correct answer. Access keys are long-term credentials that consist of an access key ID and a secret access key. They are used to authenticate and authorize programmatic access to AWS resources. The access key ID is used to identify the user or application that is making the request, while the secret access key is used to sign the request to authenticate it. These access keys can be generated and managed through the AWS Management Console, the AWS CLI, or the IAM API.
