If Z follows standard normal distribution with mean 0 and variance 1, then $$Z^{2}$$ follows:

A

Chebyshev distribution with degree of freedom 1

B

normal distribution with mean 0 and variance 1

C

0 gamma distribution with $$\alpha = 1$$ and $$\beta = 1$$

D

beta distribution with $$\alpha = 1$$ and $$\beta = 1$$
