My best guess is A.
C. does not make sense because he does not suggest that he doesn't hold high regard for Ojukwu, especially if he is happy that they announce the state of Biafra.
D. Does not because if he is really excited to share this news with his wife, he must value her opinion and reaction.
B. Could be a possible answer but announcing a state seems like a big deal, so I don't think he is EASILY provoked.
He is obviously very excited to share this news with his wife, whether she is particularly interested or not.
