France covers . . . . . . . . area of 551000 sq kms. A. a B. an C. the D. no article

The correct answer is D. no article.

The word “area” is a non-count noun, which means it does not have a plural form and does not take a determiner (such as “a” or “the”).

Here are some examples of non-count nouns:

• water
• air
• sand
• rice
• information

In the sentence “France covers 551000 sq kms,” the word “area” is used to refer to the total amount of land that France occupies. This is a non-count noun, so it does not take a determiner.

The other options are incorrect because they are all determiners. A determiner is a word that is used to specify or identify a particular noun. In the sentence “France covers 551000 sq kms,” there is no need to specify or identify the noun “area,” so no determiner is necessary.
