Which of the following is the third sentence of the passage?

The correct order of sentences would be e, b, f, d, a, g and c. The sentences a, e and g can potentially be the introductory sentences. But e is perfect for an introduction because saying thing the chronological way is the best. Also, e does not fit anywhere else because d talks about the preservation of the traces of insurance, which would follow only after a historical note on the insurance. After e is b , not f because b gives an insight into what those writings were. f follows b. After it is definitely a as it talks about its transformation and is like an introduction on where the insurance business in India today got its form from. g follows a. c obviously follows g, as ‘this company’ means Oriental Life Insurance Company in Calcutta.
