Answer:
C. Francisco Coronado.
Step-by-step explanation:
Francisco Coronado was a Spanish conquistador who led a large expedition through Arizona, New Mexico, Oklahoma, and Texas. He was also one of the first Europeans to ever discover the Grand Canyon.
But even though he led the expedition, his quest failed, for they failed to find any treasure for the Spanish empire. All of these facts are about Francisco Coronado.
Thus, the correct answer is option C.
