This sentence is split into parts, and we must find the part with a grammar or word-choice mistake.
Option A, "No stronger": This is a correct comparative phrase and needs no change.
Option B, "a figure than his": Paired with "no stronger", this correctly forms the comparison "no stronger a figure than his", so it is fine as it stands.
Option C, "is prescribed in the history": Two problems sit here. "Prescribed" means recommended or ordered, which does not fit the idea of a figure being recorded in history, so it should be "described". Also, "history" used in this general sense does not take the article "the", so the phrase should read "is described in history".
Option D, "no error": Since option C carries real mistakes, this cannot be the answer.
