You shouldn't type an answer if you are not 100% sure it goes there, no guessing!!
Read carefully all instructions!
A. Each cell contains a country: they all have different inital letters. B. The arrows indicate alphabetical order for the corresponding row/column. C. For each of the 6 continents there is a column containing 4 of its countries. D. Countries in the same column are connected either directly (ie they share a land border) or via other countries in the same column, except for 2 columns: these 2 columns contain island countries only. F. There are 6 countries that do not border any other country in the quiz. G. One column consists of multi-word countries only.
I'm not a native English speaker, but I believe there is a contradiction in the instructions:
Consider the South-America-column. By C.), there are four South American countries, and two non-South American countries. By D.), they have to be all connected, so necessarily the non-South American countries are Panama and Costa Rica, and one of the South American countries is Colombia. But now we have two countries starting with C.
