Section 11.5.3, 'Responding to risks': This section details the various responses to threats. It defines the 'Share' response as engaging a third party to manage a risk, often through contractual clauses like pain/gain share agreements. This directly supports option C.
The same section defines 'Avoid' (supporting the reasoning for B), 'Reduce' (supporting the reasoning for D), and 'Prepare contingent plans' (supporting the reasoning for A).

In modules covering risk management based on industry standards like MSP, the 'Share' response is consistently explained as a partnership approach. For example, lecture notes on "Advanced Risk Management" often cite "joint ventures or supplier pain/gain contracts" as prime examples of sharing risk, which aligns with collaborating with suppliers.
