In the context of control, the correct statement regarding rights is:

A) They must be protective rights.
B) They must be substantive rights.
C) They must arise from a legal contract.
D) They must arise as a result of future events.

In the context of control, rights should be substantive, meaning that they provide the holder with an enforceable claim or entitlement. Protective rights refer to rights that protect the holder from harm or loss, but these may not necessarily be relevant in the context of control. Rights can arise from many sources, including legal contracts, but this is not a necessary requirement. Future events may create rights, but this is not a defining characteristic of rights in the context of control.
