If the Washington, D$.$C$.,$ police department began to buy back pairs of shoes, no questions asked, for $$10$ each, economists would expect that:

the number of people wearing shoes in Washington, D$.$C$.,$ would not change at all as a result of the shoe buyback.

fewer people in Washington, D$.$C$.,$ would wear shoes as a result of the shoe buyback.

more people in Washington, D$.$C$.,$ would wear shoes as a result of the shoe buyback.

fewer people in Washington, D$.$C$.,$ would wear shoes as a result of the shoe buyback, but the average quality of those shoes would decrease.
