The T_df distribution Is Similar to the Z Distribution Because

The t_df distribution is similar to the z distribution because ___________________________________________.

A) as the degrees of freedom go to infinity,the t distribution converges to the z distribution
B) both have asymptotic tails-that is,their tails become closer and closer to the horizontal axis but never touch it
C) as the degrees of freedom go to infinity,the t distribution converges to the z distribution and both have asymptotic tails-that is,their tails become closer and closer to the horizontal axis but never touch it
D) Neither as the degrees of freedom go to infinity,the t distribution converges to the z distribution nor both have asymptotic tails-that is,their tails become closer and closer to the horizontal axis but never touch it
