Option D

Explanation:

The endowment effect is a finding in psychology and behavioural economics that states people are more likely to hold on too an object they own rather than taking that same object which they don't own. Just like I have a pen ,a blue pen to be precise, then I saw the same pen on the floor, instead of me taking that on the floor, I decide to hold on to the one I have other than taking that which is in the floor,this is called endowment effect. Option d explains more better.
