Which among the following is the last novel of George Eliot?

The correct option is Daniel Deronda.

To determine the correct answer, we can examine the chronological order of the publication dates of the novels written by Mary Ann Evans under her famous pen name, George Eliot:
1. The Mill on the Floss: Published in 1860, this is one of her earliest and most famous works, focusing on the lives of Maggie and Tom Tulliver.
2. Silas Marner: Published in 1861, this is a shorter novel about a lonely weaver who finds redemption through adopting a young girl.
3. Middlemarch: Published in serial format between 1871 and 1872, this landmark Victorian novel is a multi-layered study of life in a provincial town.
4. Daniel Deronda: Published in 1876, this was George Eliot's final completed novel. It is unique among her works for its contemporary Victorian setting and its detailed, sympathetic portrayal of Jewish culture and Zionist aspirations.

Comparing these dates shows that Daniel Deronda (1876) is indeed the last novel written and published by George Eliot during her lifetime.
