Answer:
I'm pretty sure it was C
Step-by-step explanation:
I'm not completely sure, but I just learned about this guy and
A. He did not map the Texas coast, Pineda did
B. No one found the cities of gold. They were not even real.
D. Buffalo had nothing to do with this guy.
The Spanish did not want the land, but La Salle worked for France and even though they didn't really want it as there was no gold, they didn't want France to have it either.
Again, I'm not 100% sure, more like 98% sure, so I guess you could wait until someone else answers too.
Hope this helps! :)
