Consider the following class definitions. public class Bike{private int numWheels = 2;// No constructor defined}public class EBike extends Bike{private int numBatteries;public EBike(int batteries){numBatteries = batteries;}}The following code segment appears in a method in a class other than Bike or EBike. EBike eB = new EBike(4);Which of the following best describes the effect of executing the code segment? A А. An implicit call to the zero-parameter Bike constructor initializes the instance variable numwheels. The instance variable numBatteries is initialized using the value of the parameter batteries.
B An implicit call to the one-parameter Bike constructor with the parameter passed to the EBike constructor initializes the instance variable numwheels. The instance variable numBatteries is initialized using the value of the parameter batteries.
C Because super is not explicitly called from the EBike constructor, the instance variable numWheels is not initialized. The instance variable numBatteries is initialized using the value of the parameter batteries.
D The code segment will not execute because the Bike class is a superclass and must have a constructor.
E The code segment will not execute because the constructor of the EBike class is missing a second parameter to use to initialize the numWheels instance variable.
