You are given the following code:

class Employee: """Common base class for all employees""" def __init__(self, name= " ", salary=0,date=""): self.__empName = name self.empSalary = salary self.empDate= date def printall(self): print(self.empName,self.empDate,self.empDate) x=Employee("John", 15000, "20/1/2018") print(x.empName) Which of the following is true?

		There will be an Error because it is against the object oriented programming principles
		There will be Error because 'Employee' object has no attribute 'empName' The attribute cannot be accessed.
		There will be Error because print(x.empName) should be print(x.__empName)
		The output will be John and there will be no error.
