Final answer:
Option (A) is the strongest evidence, citing the Indian Removal and the subsequent displacement of nearly 100,000 Native Americans.
Step-by-step explanation:
Among the provided options, option (A) presents the strongest piece of evidence to support the claim that government policies displaced native tribes from their lands. It details a specific historical event, the forcible relocation of nearly 100,000 native people from the southern states to "Indian Territory," present-day Oklahoma, between 1830 and 1838, known as part of the broader policy of Indian Removal. This event, enforced by federal officials, directly resulted from governmental actions.
