You have a Microsoft Power Bl semantic model.

To create a calculation item that changes the context from the selected date to month-to-date (MTD), the appropriate DAX expression involves using the CALCULATE function to alter the filter context and the DATESMTD function to specify the month-to-date context.

The correct completion for the DAX expression would be:

In the first dropdown, select CALCULATE.

In the second dropdown, select SELECTEDMEASURE.

This would create a DAX expression in the form:

CALCULATE(

SELECTEDMEASURE(),

DATESMTD('Date'[DateColumn])

)
