A login system first checks if a user exists. If the user exists, it then checks if the password is correct. If the user does not exist, it prints 'User not found'. Which code correctly implements this two-level check?

if user_exists: if password_correct: print('Login successful') else: print('Wrong password') else: print('User not found')

if user_exists: print('Login successful') if password_correct: print('Login successful') else: print('User not found')

if user_exists and password_correct: print('Login successful') else: print('User not found')

if password_correct: if user_exists: print('Login successful') else: print('User not found') else: print('Wrong password')
