Original constructor function:
01 function Vehicle(name, price) {
02 this.name = name;
03 this.price = price;
04 }
05 Vehicle.prototype.priceInfo = function () {
06 return `Cost of the $(this.name) is $(this.price)$`;
07 }
08 var ford = new Vehicle('Ford Fiesta', '20,000');
Which class definition is correct?

  constructor(name, price) {
  this.name = name;
  this.price = price;

  }
  }

  vehicle(name, price) {

  this.price = price;
  }
  priceInfo() {

  }
  }
• C.class Vehicle {
  constructor() {
  this.name = name;
  this.price = price;
  }
  priceInfo() {
  return `Cost of the ${this.name} is ${this.price}$`;
