I'm with Lenna on this one. Option D is the way to go. Although, wouldn't it be nice if we could just use a procedural command and not worry about the details? I wonder if there's an app for that...
Haha, this is a tricky one! I bet the exam writers are trying to trip us up. But I'm going with D - you can't just wave a magic wand and manipulate data without understanding what's going on under the hood.
I'm not sure, but I think option C sounds more like a declarative data manipulation language command. A procedural one would require knowledge of the data structures, right?
I think option D is the correct answer. The user needs to know how the underlying data structures are implemented in order to manipulate data using a procedural data manipulation language command.
