(a) Badami Group(P) Vindhyan
(b) Kheinjua Fm(Q) Chhattisgarh
(c) Sullavai Group(R) Kaladgi
(d) Papaghani Group(S) Cuddapah
(T) Pranahita Godavari

  • A.a-R, b-P, c-T, d-S
  • B.a-P, b-T, c-S, d-R
  • C.a-R, b-Q, c-T, d-S
  • D.a-P, b-Q, c-R, d-T

Answer: A

The correct match is a-R, b-P, c-T, d-S.

  • Badami Group - Kaladgi basin, Karnataka (it overlies the Kaladgi Supergroup).
  • Kheinjua Formation - Vindhyan basin (part of the Semri Group).
  • Sullavai Group - Pranahita-Godavari valley.
  • Papaghni Group - Cuddapah basin (its lowest group).

The other codes assign the Kheinjua Formation to Chhattisgarh or the Pranahita-Godavari valley, or the Papaghni Group outside the Cuddapah basin, which do not fit.
