Concept:The odd title is found by matching each book with its author.
Explanation:Vithobachi Shikwan, Kulkarni Leelamrut, and Shetaji Pratap were written by Mukundrao Patil.
He was a leading non-Brahman movement intellectual and editor of Din Mitra.
Shetkaryacha Asood was written by Mahatma Jyotiba Phule.
It was published in 1881.
Jyotiba Phule was a social reformer who opposed caste and untouchability.
He also started girls' schools and founded Satyashodhak Samaj.
Since the first three books share the same author, Shetkaryacha Asood is the odd title.
Answer:D. Shetkaryacha Asood
