Sorry, being an engineer at Midnight on a Friday night.

[1-10]*9 = [9,18,27,36,45,54,63,72,81,90] => 9 => D

Any number you choose will get you to the Letter "D".
List of Counties that Start with the Letter "D":

Dahomey
Daitojima
Daman
Danger Atoll
Delaware [deu]
Democratic Kampuchea
Democratic People's Republic of Korea
Democratic People's Republic of Vietnam
Democratic Republic of the Congo
Denmark [dk]
D'Entrecasteaux Islands
Desroches, Ile
Diego Garcia Island
District of Columbia [dcu]
Diu
Djibouti [ft]
Dodecanese
Dominica [dq]
Dominican Republic [dr]
Dubai
Dubayy
Ducie Atoll
Dutch Guiana

Most are not countries but sovereign territories. Others are known by
more common names. Boil it down, you now have pretty much two choices:

Denmark
Dominican Republic

If you start with "K" for animal name list of choices are:

Kangaroo
Killer Whale
King Cobra
King Crab
Kiwi
Koala
Komodo Dragon
Plus a few other, like dinosaurs and weird bird names.

Most likely choice is the kangaroo.

As for Fruits that start with the letter "O".
I searched for fruits starting with the letter O, all I could find was
one reference to Olives!!!!!!!

Soooooooo, my question is did you pick a different country or a
different animal? What was you entire Country, Fruit, and Animal
choices?

P.S. Told you I was being an engineer analyzing to the Nth Degree.
