How did the Spanish react to reports of English and French activities in North America during 1500s?

Question

a. They ignored the reports, since they already controlled Central and South America.
b. They declared war on the English and the French.
c. They built forts and Catholic missions in those areas to protect their claims.
d. They pulled out of the areas and channeled their resources in Mexico.

Answer 1

They, already, had a lot to do in the south, there wre plenty of lands and riches, they didn't bother about the northern lands at this time. Answer 'A' would be more appropriate for me.
