Exam Certified Advanced Administrator topic 1 question 118 discussion

I think it should be A

A is the most suited answer - as explained in this article - https://help.salesforce.com/s/articleView?id=sf.omnichannel_how_skills_based_routing_works.htm&type=5

A Based on the requirement, the administrator should recommend implementing Skills-Based Routing. This would allow the Support team to route cases based on specific skills or expertise required for each case. The administrator can define skills and assign them to agents, and when a new case is created, Omni-Channel automatically routes it to the most qualified and available agent based on the defined skills. Additionally, the Translation Workbench is used for translating the user interface of the Salesforce org, and it is not related to Omni-Channel routing. Queue-Based Routing and Case Assignment Rules are other routing options available in Salesforce, but they do not provide the level of complexity and flexibility required for routing cases based on specific skills or expertise.
