Pick up the correct statement from the following: A. If the flexibility is more than one, the outlet is hyper-proportional B. If the setting of an outlet is higher than that required for proportionality, the outlet is hyper-proportional C. If the flexibility is zero, it is a rigid module D. All the above

The correct answer is D. All of the above.

A hyper-proportional outlet is one that has a flexibility greater than one. This means that the outlet will produce a greater output than the input, even if the input is small. A rigid module is one that has a flexibility of zero. This means that the outlet will produce the same output regardless of the input.

If the setting of an outlet is higher than that required for proportionality, then the outlet will be hyper-proportional. This is because the outlet will be able to produce a greater output than the input, even if the input is small.

Therefore, all of the statements in the question are correct.
