Explanation:
D. makes no sense, South Africa is at least 2x larger than Botswana.
Don't go for E. The last war between the two was in, like, the 1970's
I don't know how this map shows conflict between Sudan and South Sudan, but that was caused by a political accusation u mong petty politicians, so no to C.
There is no indication this map in from the year 2010, I'd there is, I must've missed it, but no to A.
Don't go for B. because the only landscape indication is the river.
This is literally all I can tell you, I hope it has at least.
