正解:A
A standardized risk taxonomy is a common language and structure for identifying, analyzing, and reporting risks across the enterprise. It enables consistent and comparable risk assessment and aggregation, as well as clear communication and coordination among different divisions. A list of control deficiencies, an enterprise risk ownership policy, and an updated risk tolerance metric are not sufficient to enable management of risk at the enterprise level, as they do not address the issue of risk alignment and integration among divisions.
