Best Answer Explained in Below-:

The correct choice for the sentence "Choose __ the right option from the alternatives." is "C) the." This is because "the" is a definite article used to refer to a specific noun that is known to the speaker and listener. In this context, the phrase "the right option" implies that there is a particular option among the alternatives being discussed that is deemed correct or appropriate.

Using "a" or "an" would suggest the choice of any option among many, without specifying which one is right. "A" is an indefinite article used before singular nouns that begin with a consonant sound, while "an" is used for those that start with a vowel sound. However, in this scenario, we are not selecting just any option; we are indicating one specific, correct option. Therefore, saying "Choose a right option" would not communicate the same level of precision or clarity, as it weakens the assertion of correctness.

When no article is used (option D), the sentence would be grammatically awkward and incomplete. Thus, "the" is the most appropriate article to convey the intended meaning, making "C) the" the correct answer.
