A true data dependency occurs when the output of one instruction is used as input in another instruction. In this situation, the second instruction cannot execute until the first instruction produces its output. This is also known as a RAW (Read After Write) hazard. Option B, output dependency, is also a type of dependency but it occurs when the output of an instruction is used as input in a later instruction without any changes made to it. Option C, procedural dependency, is not a type of dependency in computer architecture. Option D, antidependency, occurs when the order of execution of instructions needs to be reversed to maintain correct output.
