When the program runs, suppose the user enters $4$ at the prompt.Then, which of the following steps will not occur?

A$.$First step:$4$ is passed to the factorial$()$ method.Because the value of x is not $0,$ the method should return $4$ multiplied by a call itself using the argument $3.$The method does not return yet because it must calculate factorial$(3)$ before the return statement is complete.

B$.$Second step:$3$ is passed to the factorial$()$ method.Because the value of x is not $0,$ the method should return $3$ multiplied by a call to itself using argument $2.$ The method does not return yet because it must calculate factorial$(2)$ before the return statement is complete.

D$.$Final step:$1$ is passed to the factorial$()$ method.Because the value of x is not $0,$ the method should return $1$ multiplied by a call to itself using the argument $0.$The method does not return yet because it must calculate factorial$(0)$ before the return statement is complete.
