A developer has the following class and trigger code:public class InsuranceRates {public static final Decimal smokerCharge = 0.01;}trigger ContactTrigger on Contact (before insert) {InsuranceRates rates = new InsuranceRates();Decimal baseCost = XXX;}Which code segment should a developer insert at the XXX to set the baseCost variable to the value of the class variable smokerCharge?
A. Rates. smokerCharge
B. Rates. getSmokerCharge()
C. ContactTrigger. InsuranceRates. smokerCharge
D. InsuranceRates. smokerCharge

InsuranceRates.smokerCharge

Explanation:

To set the baseCost variable to the value of the class variable smokerCharge, the developer needs to replace

Decimal baseCost = XXX;

with

Decimal baseCost = InsuranceRates.smokerCharge;

This is done using the class reference type.

The smokerCharge should be declared in the InsuranceRates class, at first.

For example Ball b;

And then, a new instance of the object from the class is created, using the new keyword along with the class name: b = new Ball();

In comparing to the example I gave in the previous paragraph, the object reference in the program is:

InsuranceRates rates = new InsuranceRates();

Because the smokerCharge is coming from a different class, it can only be assigned to the variable baseCost via the InsuranceRates class to give:

Decimal baseCost = InsuranceRates.smokerCharge;
