Final answer:
People resisted the Potlatch ban by ignoring it and secretly continuing their cultural practices, preserving their identity despite governmental attempts at assimilation. The correct option is B.
Step-by-step explanation:
People resisted the Potlatch ban primarily by ignoring the ban and continuing to participate in the ceremonies in secret.
The Potlatch was a ceremonial feast important to various Indigenous groups in the Pacific Northwest, and despite the Canadian government's efforts to suppress it through the Indian Act, many Native communities continued to practice their traditional customs clandestinely. This act of resistance helped to preserve their culture and identity.
They asserted their sovereignty by maintaining traditional practices, such as the Potlatch, which were integral to their social and ceremonial life, even in the face of governmental policies aimed at assimilation and the eradication of their cultural practices.
Hence, Option B is correct.
