Answer: A) they motivated the Spanish to search for gold
Seven cities of Cibola motivated the Spanish to search for gold.
Step-by-step explanation:
It is a myth of 16th century which was very popular. It stated that there are plenty of gold available in the seven cities of New Mexico. Though there is a strong belief in the finding of gold but no any evidence is available.
Many adventurers attempted the search and told that natives were pretty sure about the riches. Later on in 1540, the conquistador concluded about the false myth because of empty evidence, though some still believe about the myth.
