A project manager is determining the strategy and response for each risk. Which of the following would BEST allow the project manager to complete the register? (Choose two.)

Impact quantifies how severely a risk would affect project objectives such as cost, schedule, or quality; it is one of the two core metrics used to calculate a risk score and select an appropriate response strategy.

An issue is a risk that has already materialized and belongs in the issue log, not used to determine future risk response strategies.

A risk description identifies the risk but does not provide the quantitative data needed to prioritize or select a response strategy.

Cause helps trace the origin of a risk but is not used to score or prioritize risks for response planning.

Probability measures the likelihood that a risk event will occur; combined with impact, it produces the risk score that drives prioritization and response planning in the risk register.

Effect describes the outcome if a risk occurs, which is already captured under Impact, making it redundant as a standalone input for determining response strategy.
