In the following code snippet, what will be printed: dictionary = {"cat": "chat", "dog": "chien", "horse": "cheval"}; for key in dictionary.keys(): print(key, "->", dictionary[key])?

The code snippet iterates over the keys of the provided dictionary, which contains animal names in English as keys and their translations in another language as values. The for loop accesses each key in the dictionary using the keys() method and then prints the key along with its corresponding value.

When the loop runs, for each key in the dictionary, the code fetches its associated value using dictionary[key]. The output will be formatted as "key -> value" for each key-value pair. Consequently, all the keys will be printed alongside their respective values, resulting in a clear and structured output.

This behavior confirms that the correct response is the option that states all the keys of the dictionary and their corresponding values will be printed. The other options do not accurately represent the functionality of the code; for instance, choosing just the keys would ignore the values, and stating an error would imply there's an issue in the syntax or logic, which is not the case here.
