A. Have access to the customer's signed contract.
A contract establishes the business engagement but does not serve as a direct authorization for technical system access, which requires a separate, explicit approval process.
C. Assign the customer to your Provisioning ID.
This is a technical step that SAP performs to grant access after the customer has formally approved the partner's request. It is a result of approval, not a prerequisite.
D. Enable Company Settings in Provisioning for the customer.
This is an action performed inside the Provisioning system. Therefore, you must already have access to perform this task, making it impossible to be a prerequisite for requesting access.
