With LiveConnection we can connect a PBI report to a Semantic Model but question is about "connectivity mode should you use for the dataset" so the answer should be DirectQuery (note: Dataset is the former name of current Semantic models)

Push Mode in Power BI refers to a real-time streaming capability where data is pushed into a Power BI dataset directly via APIs or other services, enabling real-time updates in reports and dashboards. It is designed for scenarios where data needs to be updated continuously without the need for a manual or scheduled data refresh.

Should be C. The power bi semantic model that's connected to the live streaming data source already is created and exists. You want to build a report by connecting to that semantic model, therefore you should just connect to it as a live dataset.

Live connection and DirectQuery comparison https://learn.microsoft.com/en-us/power-bi/connect-data/service-live-connect-dq-datasets Live connection is a method that lets you build a report in Power BI Desktop without having to build a semantic model for it. The semantic model can dynamically request data from a data source it's connected to using a method called DirectQuery. When using DirectQuery, your report uses Data Analysis Expression (DAX) queries to get data. After the semantic model receives the report's DAX query, it generates another set of queries that are run on your data source, to get the required data. From this I am concluding use DirectQuery.

Push isn’t a type of connectivity. It’s a kind of semantic model
