Exam SCR topic 1 question 68 discussion

The CRO for a large agriculture company reviews reference scenarios as part of an annual climate scenario analysis exercise. The CRO creates a transition risk matrix that compares four different scenarios - W, X, Y, Z. Scenarios are compared according to scale of emissions cuts and pace of emission cuts.

How should the CRO rank the reference scenarios from lowest level of transition risk to highest level of transition risk?
