Final answer:
Atlantic Canada was affected by the National Policy, making option A) not true.
Step-by-step explanation:
The correct answer is A) It was not affected by the National Policy.
Atlantic Canada, which consists of the Maritime Provinces (New Brunswick, Nova Scotia, and Prince Edward Island) as well as Newfoundland and Labrador, was indeed affected by the National Policy. The National Policy was an economic and political strategy implemented in the late 19th century by the Canadian government to promote economic growth and protectionist policies. While the National Policy sought to develop Canadian industries and protect them from foreign competition, it had a negative impact on Atlantic Canada due to its reliance on primary industries such as fishing and forestry.
Therefore, option A) is not true.
