A company has a base class Employee with attributes name and salary, and a method get_info(). They need a subclass Manager that adds a department attribute and overrides get_info() to include the department. Which class definition correctly implements this?

class Manager(Employee): def __init__(self, name, salary, department): self.department = department def get_info(self): return f"{self.name} manages {self.department}"

class Manager(Employee): def __init__(self, name, salary, department): super().__init__(name, salary) self.department = department def get_info(self): return super().get_info() + f" in {self.department}"

class Manager(Employee): def __init__(self, name, salary, department): self.name = name self.salary = salary self.department = department

class Manager(Employee): def __init__(self, name, salary, department): Employee.__init__(self, name, salary) self.department = department

A developer is refactoring a class hierarchy. The subclass Dog inherits from Animal. The Animal class has a method speak() that returns "Some sound". The Dog class should override speak() to return "Woof" but also call the parent's speak() to log the action. Which code correctly does this?

def speak(self): return super().speak() + " Woof"

def speak(self): print(super().speak()) return "Woof"

def speak(self): parent_msg = super().speak() return "Woof"

Given the following class definitions: class Vehicle: def __init__(self): self.wheels = 4 def start(self): return "Vroom" class Car(Vehicle): def __init__(self): super().__init__() self.color = "red" def honk(self): return "Beep" Which statement correctly identifies the properties and methods of a Car object?

Car has properties wheels and color, and methods start and honk.

Car has only the color property and the honk method.

Car has wheels, color, and start properties, and honk method.

Car has wheels and color properties, but only the start method.

An e-commerce system defines a class Product with an __init__ method that sets self.name and self.price. The developer wants to create a product and then apply a 10% discount to its price. Which code snippet correctly does this?

p = Product("Laptop", 1000) p.price = p.price * 0.9

p = Product("Laptop", 1000) Product.price = 900

p = Product("Laptop", 1000) p.apply_discount(10)

p = Product("Laptop", 1000) p.price = 900
