Correct article before the name of country in French

Bonjour Manjinder kaur, 

Here are links on countries and gender, which I hope will be useful:

using-le-la-l-les-with-continents-countries-and-regions-names

continents-countries-regions-states-names-are-either-feminine-masculine-or-plural-gender

say-where-you-come-from-with-venir-de-d-du-des-country-state-region

Countries / Les pays

As Maarten mentioned, you might also need to do a bit of research online or in a dictionary, as not all countries and their gender are listed on Kwiziq.

I hope this is helpful.

Bonne journée !
