A C
public static void main(String[] args) {
double discount = 0;
int qty = Integer.parseInt(args[0]);
//A
// if(qty>=90){discount=0.5;}
// if(qty >80 && qty=90 ? 0.5 : (qty>80)? 0.2 : 0 );
System.out.println(discount);
}
Answer A, C:
B and D are not correct because there is two conditional statements and in each one there is an else statement that is assigning the value of discount to 0. While D is not correct because the (qty >= 90) is unreachable and would always equal to false.
