-
Functions
-
All of the above
B
Correct answer
Explanation
In SSRS (SQL Server Reporting Services), cascading parameters are typically implemented through stored procedures where one parameter's value is used to filter available values for another parameter. The stored procedure can accept the first parameter as input and return filtered options for the dependent parameter. Variables and functions alone don't provide the mechanism for parameter dependency.
