def most_common_key(d: dict) -> list:

'''

Given d representing the number of occurrences of each

key within the data set analyzed, give a list of the keys

that occur the most frequently.

Note: there could be multiple keys that occur

most frequently, which is why we're returning a list.

If there is only one most frequent key, the returned value

would just be a list of one element that is that key.
