Explanation:
A responsibility refers to something that more or less you've personally decided upon being being accountable for. You feel personally obligated to do that thing. A duty, is typically assigned to you. Although, they coincide.
For example you have a responsibility to choose healthy meals or foods to eat; you have a duty to show up to work on time.

The answer is C :) because duty is something someone has to do but a responsibility is something that someone should do
