Which statement is true of an output context operator?

The dimension list uses brackets, but the output context operator itself is not placed within those brackets - the dimensions are listed inside the operator's own bracket set.

Being placed outside the dimension list brackets describes the operator keyword position relative to its own argument list, which does not answer where it sits relative to the aggregation function.

The brackets of the aggregation function contain the measure expression (e.g., [Sales]), not the context operator; placing a context operator inside would produce a syntax error.

The output context operator (In, ForEach, ForAll) is placed outside and after the closing bracket of the aggregation function. For example, the correct syntax is Sum([Sales]) In ([Country]), where 'In ([Country])' follows the function's closing bracket, overriding the default output context for that calculation.
