c. fremont
Step-by-step explanation:
James C. Fremont was a major in the army of the United States and led many expeditions to the west and thus got the title of 'Pathfinder". He became the first candidate to run for the office of President from a republican ticket. His expedition in American Mexican war to get the control of California in 1846 gave him a huge prestige followed by constant rift with government. In the history of the United States, he marks his name for his military heroism.
