Answer:
(C) established a series of missions roughly one-day's walk apart along
California's coast
Explanation:
Franciscan fathers established the California missions along El Camino
Real (the King's Highway) in locations approximately one-day's walk
apart. Mission administrators were criticized both in Mexico and Spain
for cruel and exploitative practices involving Indians living near the
missions. Concentrating populations near the missions resulted in the
rapid spread of disease. Alta ("upper") California never proved to be a
profit center for Spain, which relinquished its control with Mexico's
independence in 1821.
