The problem statement now leads you to the letter D, which generally leads to the selection of Denmark as a country, since no other common country starts with that letter. Similarly, the letter K invariably leads to kangaroo as an animal, with only Kuala Bear as a possible contender. The kangaroo is larger, and, in the spirit of the problem, should be the proper choice.
