When reviewing a business continuity plan (BCP).

According to the CRISC Review Manual, recovery time objectives (RTOs) are the maximum acceptable time that an IT system can be inoperable without causing significant damage to the business operations and objectives. RTOs are determined by the business impact analysis (BIA) and are used to define the recovery strategies and priorities. Therefore, if the RTOs do not meet the business requirements, it would be themost significant deficiency in the BCP, as it would imply that the recovery plan is not aligned with the business needs and expectations. The other options are not the most significant deficiencies, as they do not directly affect the recovery time and the business continuity. BCP testing is not necessarily done in conjunction with the DRP, as they have different scopes and objectives. BCP testing can use different methods, such as walk-through, simulation, or full interruption, depending on the purpose and scope of the test. Each business location can have separate BCPs, as long as they are consistent with the enterprise-wide BCP and the business requirements. References = CRISC Review Manual, 7th Edition, Chapter 5, Section 5.2.2, page 240.
