Bdef WaitForTitle(title): return driver.title == title

Cclass WaitForTitle: def check(self, driver): return driver.title == self.title

Dclass WaitForTitle: def __init__(self, title): self.title = title def call(self, driver): return driver.title == self.title

Step 1: Recognize the required method
Custom expected conditions must implement __call__(self, driver) to be callable by WebDriverWait.

class WaitForTitle: def __init__(self, title): self.title = title def __call__(self, driver): return driver.title == self.title correctly defines __call__ and uses the driver parameter.
Final Answer:
class WaitForTitle: def __init__(self, title): self.title = title def __call__(self, driver): return driver.title == self.title correctly implements the custom expected condition class.
