Kenya, which adjoins Uganda, seeks to protect a species of African elephants that tends to travel in groups across borders. The elephants are at risk of extinction because of poaching. The best tactic to protect this species would be for Kenya to:

a. Litigate this matter at the ICJ.

b. Have this species placed on the "endangered list" of the Convention on International Trade in Endangered Species (CITES).

c. Increase the monetary penalties for poaching in that country.

d. Confine all elephants of that species in zoos all across the world.
