Final answer:
The question about the House of Commons seats is not directly answerable with the given options as they are all populous provinces and thus would not have the lowest number of seats. For the Quebec Act, the provision was the extension of Quebec's boundaries into the Ohio Valley.
Step-by-step explanation:
The province that gets the lowest number of seats in the House of Commons is not clearly stated in the provided information. However, it is generally the province with the smallest population that would receive the fewest seats. Among the options presented, none of the provinces (Ontario, British Columbia, Alberta, Quebec) holds the status of having the lowest number of seats, since they are among the more populous provinces. The territories or smaller provinces such as Prince Edward Island would typically have the least number of seats.
To more accurately answer the question about the Quebec Act, one of the provisions was that the boundaries of Quebec were extended into the Ohio Valley. This is the correct answer to the exercise question provided.
