For a proportional outlet, the flexibility is A. zero B. between zero and 1 C. 1 D. greater than 1

The correct answer is: B. between zero and 1.

A proportional outlet is a type of outlet that allows for a variable amount of power to be delivered to a load. The flexibility of a proportional outlet is the range of power levels that can be delivered. A proportional outlet

with a flexibility of 0 can only deliver one power level, while a proportional outlet with a flexibility of 1 can deliver any power level between 0 and the maximum power level.

Option A is incorrect because a proportional outlet can deliver a variable amount of power, so it cannot have a flexibility of zero. Option C is incorrect because a proportional outlet can deliver a range of power levels, so it cannot have a flexibility of 1. Option D is incorrect because a proportional outlet cannot deliver more power than the maximum power level, so it cannot have a flexibility greater than 1.
