Explanation:

This question tests knowledge of famous Indian authors and their literary works, specifically asking to identify the mismatched pair. - **Option (A) Jaishankar Prasad - Kamayani:** This pair is correctly matched. Jaishankar Prasad was a towering figure in modern Hindi literature, particularly associated with the Chhayavaad (Romanticism) period. 'Kamayani' is his magnum opus, an epic Hindi poem that is considered a masterpiece of the era. Therefore, this is a correctly matched pair. - **Option (B) Harivansh Rai Bachhan - Madhushala:** This pair is correctly matched. Harivansh Rai Bachchan was an eminent Hindi poet, and 'Madhushala' is one of his most celebrated and iconic collections of رباعیات (quatrains), known for its philosophical and lyrical depth. Therefore, this is a correctly matched pair. - **Option (C) Mahadevi Verma - Godan:** This is the mismatched pair, making it the correct answer to the question. Mahadevi Verma was a distinguished Hindi poetess and a leading figure of the Chhayavaad school, known for her poignant poetry and prose. Her famous works include 'Yama,' 'Deepshikha,' and 'Neehar.' 'Godan,' on the other hand, is a classic Hindi novel written by Munshi Premchand, a renowned realist writer. 'Godan' vividly portrays the socio-economic realities and struggles of rural India. Therefore, attributing 'Godan' to Mahadevi Verma is factually incorrect. - **Option (D) Maithalisharan Gupt - Saket:** This pair is correctly matched. Maithilisharan Gupt was an eminent Hindi poet, often honored with the title 'Rashtrakavi' (National Poet). 'Saket' is one of his most significant epic poems, which reinterprets and expands upon themes from the Ramayana. Therefore, this is a correctly matched pair.\nHence, the mismatched pair is Mahadevi Verma - Godan.
