A school administrator announces that a new policy has

increased the number of students who adhere to the dress code

to $90\%,$ but a student counts $20$ students and notices that only $16$

adhere to the dress code. The student decides to use a

simulation with $30$ trials to test whether the administrator's claim

is valid. For each trial, the student plans to randomly generate $20$

single$-$digit numbers with the intent of counting the number of

digits that represent students who adhere to the dress code.

Which method of assigning values to the random numbers will

achieve the goal of the simulation?

A$.$ Let $0-1$ represent students who adhere to the dress code

and $2-9$ represent students who do not adhere to the

dress code.

B$.$ Let $0-3$ represent students who adhere to the dress code

and $4-9$ represent students who do not adhere to the

dress code.

C$.$ Let $0-2$ represent students who adhere to the dress code

and $3-9$ represent students who do not adhere to the

dress code.

D$.$ Let $0-8$ represent students who adhere to the dress code

and $9$ represent students who do not adhere to the dress

code.
