The correct answer is C. Draw custom path.
The Draw custom path tool allows you to create a path by clicking and dragging your mouse. You can use this tool to create straight lines, curves, freeform shapes, and scribbles.
The Create effect tool allows you to add effects to objects, such as drop shadows, glows, and bevels.
The Insert motion path tool allows you to add a motion path to an object, which will cause the object to move along the path when the document is played.
Therefore, the only option that allows you to select line, curve, freeform or scribble tools is C. Draw custom path.
