The correct pair of Indian petroleum producing area and its location is

Concept

A petroleum-producing area requires a documented record of hydrocarbon extraction or output; exploration or prospectivity alone does not establish production.

To evaluate an area–location pair, verify both the production record and the geographic location. For a “more than one” choice, check each pair independently and count the valid pairs.

Application

1. Historical Assam records place the Badarpur and Masimpur oil fields in Cachar within the Surma Valley and record crude-oil output from them.

2. Government records identify Lunej-1 in the Cambay region of Gujarat as a hydrocarbon discovery well that produced oil and gas.

3. The Directorate General of Hydrocarbons places the Krishna–Godavari Basin offshore in the Bay of Bengal and records commercial hydrocarbon output, including production from its deep-water gas fields.

Contrast and cross-check

• All three named area–location pairs have supporting production and location records, so the valid-pair count is greater than one.

• The official BPSC final answer key for this paper independently records the set-level answer “More than one of the above”; “None of the above” is excluded by the documented matches.
