Answer:
B.
Step-by-step explanation:
Isaac Stevens was appointed as a governor of Washington territory in 1853. In his governorship, Stevens took the first task to force treaty on Indians residing on the west of Washington.
The desired outcome that Stevens had in his thought, for the negotiations with the Native Americans was to move Indians to the reservation land. He, like many other Americans, believed that the Indians were hindrance for the development of American civilization in Washington. So, he forced treaties on Indians and removed them from their Native Lands, and moved them to the lands undesired by Americans.
Therefore, option B is correct.
