Final answer:
Aboriginal people in Canada were granted the right to vote in federal elections in 1960 according to the Indian Act.
Step-by-step explanation:
The Aboriginal people were granted the right to vote in federal elections in 1960 as stipulated by the Indian Act. Before this historical landmark, First Nations women could not vote in band council elections until 1951, and they were not allowed to run for band office until 1964. It wasn't until the mid-20th century that all women in Canada, regardless of racial origin, gained the full right to vote and hold office at all levels of government. Hence, the correct answer to the question is B) 1960.
