Final answer:
Option (C), Father Antonio de Olivares founded the most successful Texas mission, San José y San Miguel de Aguayo, while Father Miguel Hidalgo is known for his role in Mexico's independence.
Step-by-step explanation:
The priest who founded the most successful Texas mission, San José y San Miguel de Aguayo, was Father Antonio de Olivares. Father Miguel Hidalgo, while a significant historical figure, was not known for founding missions, but rather for initiating Mexican independence with the Cry of Dolores.
Despite his revolutionary efforts leading to his capture and execution, he is celebrated as a national hero in Mexico, with the country's Independence Day marking the date of his famous cry for independence. Father Hidalgo's role was vastly different from that of Father Antonio de Olivares, who is associated with the establishment of missions in Texas.
