The curve of the probability density function for a random variable $X$ can be described by all of the following properties EXCEPT

A

the total area under the curve is equal to $1$.

B

$Pr[X=a]=0$ for any value $a$ of the variable $X$.

C

the curve helps describe the probability of a range of particular outcomes of $X$.

D

the curve helps describe the probability of a particular outcome of $X$.

E

the curve can be described using four statistics: mean, variance, skewness, and kurtosis.
