The British North America Act was passed by the British Parliament in:

Discover Canada records this in one direct sentence about Canadian Confederation. The guide writes: The British Parliament passed the British North America Act in 1867. The Dominion of Canada was officially born on July 1, 1867. The year the test wants is therefore 1867.

Two paired commitments. Discover Canada commits the founding of Canada to TWO specific facts: (1) the British Parliament passed the British North America Act in 1867; (2) the Dominion of Canada was officially born on July 1, 1867. So the British North America Act and the Dominion of Canada were both 1867 events — the parliamentary statute and the country itself.

The Act has constitutional standing. Discover Canada commits the British North America Act to a specific named status: it was Canada's "original constitutional document in 1867." So the BNA Act is named in the source as the founding constitutional document of Canada. The Act includes "Peace, Order and Good Government" — a key phrase that names the Canadian governing tradition. So the 1867 Act is not just any law but the constitutional foundation of the country.

The Fathers of Confederation were the named builders. Discover Canada commits Confederation's authorship to a named group: "The Fathers of Confederation established the Dominion of Canada on July 1, 1867, the birth of the country that we know today." Among the named Fathers are Sir Étienne-Paschal Taché, Sir George-Étienne Cartier, and Sir John A. Macdonald — the latter became the first Prime Minister of the Dominion of Canada. The 1867 BNA Act gave Canada its first formal federal structure: the new Dominion brought together the existing British North American colonies into a single federation. July 1 was originally celebrated as "Dominion Day" — until 1982, when it was renamed Canada Day. The 1867 founding remains the single most important date in Canadian political history. So when the test asks the year the British Parliament passed the British North America Act, the source-precise answer is 1867.

The question is testing whether new citizens know the year of the British North America Act. Discover Canada commits to one year: 1867. The right test answer matches that.

The wrong answer choices each pick a different year. The first choice — 1776 — is the year the 13 American colonies declared independence and formed the United States, not the year of the BNA Act. The second choice is not named in the source for the BNA Act. The fourth choice is far too late; the source places the BNA Act at 1867. Only 1867 — the source's exact named year — matches.
