The correct answer is Confidentiality integrity and availability targets.

The development team should define protection levels as Confidentiality integrity and availability targets because these properties articulate the core objectives for protecting data. Confidentiality specifies who is allowed to access data, integrity ensures the data remains accurate and trustworthy, and availability defines acceptable uptime and recovery expectations. Setting targets for these dimensions guides selection of controls encryption, access control, validation, backups, and monitoring and it informs testing and incident response priorities.

Detection and correction of software errors is primarily about finding and fixing bugs and improving software quality and reliability. Those activities support security but they do not define the data protection properties that the development team must set.

Cloud Identity and Access Management is an implementation mechanism for enforcing who can access cloud resources and data. It is a useful control for achieving confidentiality and access management but it is not the set of protection properties to be defined as targets.

Authentication and nonrepudiation mechanisms are specific controls that help verify identities and ensure actions cannot be denied. They support integrity and accountability but they are not the overarching protection level properties which are confidentiality integrity and availability.
