How would communitarian Alasdair MacIntyre respond to the claim that our loyalties to family and country are contingent attachments that should carry no moral weight?

A$.$ Although I inherit my family and country by chance, such loyalties are parts of a meaningful narrative and, in this sense, not contingent.

B$.$ Although we should consider such loyalties when judging how to act in our private lives, such loyalties should not ground political obligation.

C$.$ We ought always to follow such loyalties, even if it means committing injustices.
