The correct answer is 0.

Here's the step by step explanation:

1. The `collections.defaultdict` function is a dictionary subclass that calls a factory function to supply missing values. In other words, it does not raise a KeyError when you try to access a non-existent key. Instead, it will create any items that you try to access (provided they do not exist yet).

2. In this case, `collections.defaultdict(int)` is used, which means that if a key is not found in the dictionary, then instead of a KeyError being thrown, a new entry is created. The `int()` function returns 0, so every new key that you try to access in the dictionary will have a value of 0.

3. Therefore, when you try to print `ct[2]`, Python will return 0 because this key was not in the dictionary, so it was created with a value of 0.
