a. custer and his force arrived after the main u.s. force.
b. custer and his force arrived ahead of the main u.s. force.
c. custer and his force were unprepared for the sioux attack.

Explanation:

At the Battle of Little Bighorn, Custer made critical errors: he split his forces and advanced ahead of the main U.S. military column, and he severely underestimated the size and strength of the combined Sioux and Cheyenne forces, leaving his troops unprepared for the large-scale attack that overwhelmed them. Both factors directly led to his defeat.

Answer:

B. Custer and his force arrived ahead of the main U.S. force.
C. Custer and his force were unprepared for the Sioux attack.
