Answer: a. Wise
Explanation:
At the beginning of the story (Federigo's Falcon) it was shown that Federigo was a very RICH and RESPECTED man who lavished Monna Giovanni with a lot of gifts as well as holding sumptuous banquets.
It was also shown that he was of Nobel birth.
The fact that he kept spending money on lavish gifts and parties without taking anything in however, and eventually becoming poor showed that he was not a WISE man because a wise man should know how to keep his finances balanced.
