In 2017 which executive was appointed as Chairman and Managing Director of Hindustan Copper Limited HCL a public sector enterprise in the mining sector

Introduction / Context:
Hindustan Copper Limited HCL is a central public sector enterprise engaged in copper mining and production in India. Leadership changes in such public sector companies are part of economic and business current affairs. In 2017 a new Chairman and Managing Director CMD was appointed to head HCL and this question asks you to identify that person.

Given Data / Assumptions:

• The organisation is Hindustan Copper Limited.
• The position is Chairman and Managing Director CMD.
• The year of appointment mentioned is 2017.
• Four options are given each representing a different name.

Concept / Approach:
This is a straightforward current affairs recall question. The strategy is to connect the name of the public sector company with announcements in newspapers or government notifications about top level appointments. In many exams such questions frequently appear so regular reading of business sections is essential.

Step-by-Step Solution:
Step 1: Note that the question is specific to Hindustan Copper Limited HCL. Step 2: Recall that in 2017 Santosh Sharma was appointed as Chairman and Managing Director of HCL. Step 3: Check the options and find that Santosh Sharma appears as option D. Step 4: The other names Debasis Jana Sankara Rao and Dev Patel are not linked with this particular appointment in widely reported sources. Step 5: Therefore select Santosh Sharma as the correct answer.

Verification / Alternative check:
You can verify by remembering that press releases from Hindustan Copper Limited and coverage in financial newspapers clearly stated that Santosh Sharma who had earlier served as Director Operations at HCL took charge as CMD in 2017. No similar announcements connect the other individuals listed in the options with the top leadership of this specific company.

Why Other Options Are Wrong:
Debasis Jana may be associated with other organisations but not as CMD of Hindustan Copper Limited in 2017. Sankara Rao is not known as the CMD of HCL in that period. Dev Patel is not related to the leadership of this public sector mining company.

Common Pitfalls:
A common error is to guess based on which name sounds familiar in general rather than in the specific context of Hindustan Copper. Another pitfall is confusing HCL Hindustan Copper Limited with private sector technology companies that share similar initials. Always anchor the name of the person to the correct industry and enterprise while revising.

Final Answer:
The person appointed as Chairman and Managing Director of Hindustan Copper Limited in 2017 was Santosh Sharma.
