Answer :
The character trait that Kelvin demonstrates is honesty.
Explanation:
By returning the wallet to its rightful owner, Kelvin showed that he is honest. A person who is honest tells the truth, is not likely to lie, cheat, or steal, and can be trusted. Kelvin could have simply taken the wallet and kept it along with all of the money it contains. This would've been done with no consequences, as it isn't likely that anyone would find out that he took a wallet someone else had lost. But, instead, he decided to be honest and return the wallet to its owner, saving the woman a lot of trouble.
