D.P Q S R
Explanation
After S1 introduces the Vindhyan basin, P naturally follows with 'One branch of the basin extends from Sasaram to Hoshangabad'. R then describes 'This branch of this basin occupies a large continuous area'. S adds 'Several isolated exposures of sedimentary rocks occur in the Bastar area'. Finally, Q mentions the diamond-bearing conglomerates found in some Vindhyan exposures, leading naturally to S6 about diamond-producing districts. Hence the correct order is P R S Q, option (a).
