Correct answer is A. Uniform distributions can be used if there is no obvious value that is more likely than any other between specified high and low bounds, such as in the early concept stage of design.

Answer A is correct. A uniform distribution is a type of probability distribution in which all outcomes are equally likely. It is also known as a rectangular distribution because the probability density function of the uniform distribution is a constant within the given range and zero outside the range. The uniform distribution does not have any specific parameters; it only contains the minimum and maximum values of the range. It is also the most commonly used probability distribution in uncertainty analysis.
