Fill in the blank with the most appropriate option.
Jack is not only a good student ____ a fine athlete.
(a)rather than
(b)as well as
(c)but also
(d)in addition

Hint: Conjugation is a class of verbs having the same inflectional forms. It is the complete set of inflected forms of a verb.

Complete answer:In the given question, we have to find out which of the options given to us is used in a sentence with a contradiction, as generally, being a good student and a good athlete are seen as two opposing or very different qualities.
Let us thus analyze the options given to us in this question:
(a)'rather than', is used to indicate that the following alternative is less preferred’.
Therefore, option (a) is incorrect as it is not relevant to the context of the sentence.
(b)‘as well as', refers to ‘And in addition.’
Therefore, option (b) is incorrect as a sentence with ‘not only’ cannot use ‘as well as’ for conjugation as it does not present any contradiction.
(c)‘but also', refers to but, which means ‘On the contrary, but rather (introducing a word or clause that contrasts with or contradicts the preceding clause or sentence without the not).’
Therefore, option (c) is correct as it presents the contradiction and also a conjugation due to the use of ‘also’.
(d)‘in addition', refers to ‘also; as well; besides.’
Therefore, option (d) is incorrect as it is not relevant to the context of the sentence.

Note:In this question, it will be helpful for the student to recall the concept of a phrase.A phrase is an expression consisting of one or more words forming a grammatical constituent of a sentence.
