What is the result?

Given the definition of the Vehicle class:
Class Vehhicle {
int distance; //line n1
Vehicle (int x) {
this distance = x;
}
public void increSpeed(int time) { //line n2
int timeTravel = time; //line n3
class Car {
int value = 0;
public void speed () {
value = distance /timeTravel;
System.out.println (“Velocity with new speed”+value+”kmph”);
}
}
new Car().speed();
}
}
and this code fragment:
Vehicle v = new Vehicle (100);
v.increSpeed(60);
What is the result?

A.
Velocity with new speed

B.
A compilation error occurs at line n1.

C.
A compilation error occurs at line n2.

D.
A compilation error occurs at line n3.
