Explanation:

Correct answer is (c). The words ‘man’ and ‘woman’ are used without ‘the’ before generalizations concerning singular countable nouns. The article ‘the’ would have been used if any specific or definite objective was served by the noun. E.g. The man I met yesterday is working in my office. Thus the error is in the 3^rd part of the sentence. The correct sentence should read – ‘Literature often celebrates the fact that man is a mortal being.’ Hence, the correct answer is option c.
