Answer:
C.) The Europeans understood that this victory was a Christian victory against the Muslim invaders.
Step-by-step explanation:
The attacks from the Muslims in the Iberian Peninsula would continue after the victory of Charles Martel, but they would never become an outright invasion. Tours represented the pinnacle of the Muslim expansion in the West, and was seen as a great victory of the Christian kingdoms against Islam. The Frankish kingdom would later, in the reign of Charlemagne establish the Hispanich March as a buffer zone against the Muslims.
