Answer:
The answer is "Option A".
Explanation:
Please find the complete program in the attached file.
The given program includes a super-class Bike having a private integer numWheels parameter. The class EBike inherits the class Bike, EBike comprises one parameter function Object() which utilizes its variable number of the private integer Battery level of the battery parameter and the wrong choice can be defined as follows:
In choice B, it is wrong since there is no constructor with a single argument in the Bike class.
In choice C, it is wrong since there no need to call the base class constructor with the super keyword.
In choice, D is wrong because there no need to create a constructor of the base class.
In choice, E is wrong because it does not require the second EBike constructor parameter.

Explanation:
The following is written in Java. It creates the trafficLight class which holds the currentLight string variable and a int count variable for the number of times the light has been red. It also contains two constructors one that takes the currentLight as a parameter and one that does not. Finally, it has the next() method which analyzes the currentLight status and changes it to the next light. Output can be seen in the attached picture below.
class Brainly
{
public static void main(String[] args)
{
trafficLight traffic_light = new trafficLight();
System.out.println("Current Light: " + traffic_light.currentLight);
traffic_light.next();
System.out.println("Current Light after change: " + traffic_light.currentLight);
}
}
class trafficLight {
String currentLight;
int count = 0;
public trafficLight(String currentLight) {
this.currentLight = currentLight;
}
public trafficLight() {
this.currentLight = "red";
count++;
}
public void next() {
if (this.currentLight == "green") {
this.currentLight = "yellow";
} else if (this.currentLight == "yellow") {
this.currentLight = "red";
count++;
} else {
this.currentLight = "green";
}
}
}
