A developer is creating a `Vehicle` class with a method `move` that prints the vehicle's speed. The method should use the instance attribute `speed`. Which code snippet correctly defines this method?

class Vehicle: def move(self): print(self.speed)

def move(self): print(self.speed)

class Vehicle: def move(): print(speed)

class Vehicle: def move(self): print(speed)

A developer is building a `BankAccount` class for a fintech startup. They need to ensure that each account's balance is stored on the instance, not shared across all accounts. The developer writes a method `deposit(self, amount)` that should update the balance. Which method body correctly achieves this?

`BankAccount.balance += amount`

A `Car` class has a method `set_speed(self, speed)` that sets `self.speed = speed`. After creating `car1 = Car()` and `car2 = Car()`, which sequence of calls will set `car1.speed` to 50 and `car2.speed` to 60?

`car1.set_speed(50); car1.set_speed(60)`

`Car.set_speed(50); Car.set_speed(60)`

`car1.set_speed(50); car2.set_speed(60)`

A developer is creating a `Calculator` class and wants to define a method `multiply(self, a, b)` that returns the product. Which code snippet correctly defines this method?

`def multiply(a, b): return a * b`

`def multiply(self, a, b): return a * b` (but indented with a tab)

`def multiply(self, a, b) return a * b`

`def multiply(self, a, b): return a * b`
