Answer:
c. "Elsewhere."
Explanation:
Blantyre is a city in Malawi in East Africa. A volunteer of a Peace Corps stated that there are two letter slots held in the post office of Blantyre. One of the slots was labeled as "Blantyre" while the other was labeled as " Elsewhere".
This is because there are two slots. One slot is reserved for Blantyre and other slot is for from all the other elsewhere places.
