A developer is building a `BankAccount` class for a financial application. Each account must track its own balance, and the `deposit` method must update the balance for the specific instance on which it is called. Which method implementation correctly uses `self` to maintain per-instance state?

def deposit(self, amount): balance += amount

def deposit(self, amount): self.balance += amount

def deposit(amount): balance += amount

def deposit(amount): self.balance += amount

In a `GameCharacter` class, the `take_damage` method needs to reduce the character's health by a specified amount. The method also needs to call `check_status` to see if the character is defeated. Which code correctly uses `self` to achieve both?

def take_damage(self, amount): health -= amount check_status()

def take_damage(self, amount): self.health -= amount self.check_status()

def take_damage(self, amount): health -= amount self.check_status()

def take_damage(self, amount): self.health -= amount check_status()
