A) The density function of an exponential distribution with parameter 1 is e^(-x).
B) The mean of an exponential distribution with parameter 1 is 1/1 = 1.
C) The standard deviation of an exponential distribution with parameter 1 is 1/1 = 1 and the variance is (1/1)^2 = 1.
Therefore, all of the choices are true.
