The correct answer is C. independent of each other.
A flip-flop is a device that stores one bit of information. It has two stable states, which can be represented by 0 and 1. The output of a flip-flop is determined by its input and its previous state.
The outputs of a flip-flop are always independent of each other. This means that the output of one flip-flop does not affect the output of another flip-flop.
Option A is incorrect because the outputs of a flip-flop are not always complimentary. This means that the output of one flip-flop is not always the opposite of the output of another flip-flop.
Option B is incorrect because the outputs of a flip-flop are not always the same. This means that the output of one flip-flop is not always the same as the output of another flip-flop.
Option D is incorrect because the outputs of a flip-flop are not always the same as the inputs. This means that the output of one flip-flop is not always the same as the input of another flip-flop.
Option E is incorrect because the outputs of a flip-flop are always independent of each other.
