The uranium mines being developed by UCIL at Lambapur and Domiasiat are located, respectively, in which of the following pairs of Indian states?

Introduction / Context:
This question tests knowledge of strategic mineral resources in India, specifically uranium deposits. UCIL (Uranium Corporation of India Limited) is responsible for mining and processing uranium ore in India. Lambapur and Domiasiat are two important uranium projects, and exams often ask which states host these deposits.

Given Data / Assumptions:
- Two uranium mine sites are named: Lambapur and Domiasiat.
- The options provide different pairs of states in which these sites might be located.
- The question asks for the correct pairing of states for Lambapur and Domiasiat, respectively.
- Lambapur was identified in what was then Andhra Pradesh (now the area falls in Telangana), but traditional exam keys still use Andhra Pradesh as the answer.

Concept / Approach:
Lambapur is a uranium deposit located in the Nalgonda region, which historically belonged to Andhra Pradesh and later became part of Telangana after state bifurcation. Domiasiat, also known as Domiasiat–Wahkyn, is a major uranium deposit in the West Khasi Hills of Meghalaya in northeastern India. The classical GK pairing, based on older state boundaries, is "Andhra Pradesh and Meghalaya". The approach is to recall this conventional pairing as used in exam literature, while being aware of the later formation of Telangana.

Step-by-Step Solution:
Step 1: Identify Lambapur as a uranium mining project originally associated with Nalgonda district in undivided Andhra Pradesh.Step 2: Identify Domiasiat as a significant uranium deposit located in the West Khasi Hills region of Meghalaya.Step 3: Examine the options and find which pair correctly matches Andhra Pradesh (for Lambapur) and Meghalaya (for Domiasiat).Step 4: Option (c) lists Andhra Pradesh and Meghalaya, which matches the traditional mapping.Step 5: Other options mention pairs like Jharkhand and Arunachal Pradesh, West Bengal and Assam, or Maharashtra and Sikkim, none of which correspond to these particular uranium mines.Step 6: Therefore, the correct answer according to standard GK is Andhra Pradesh and Meghalaya.

Verification / Alternative check:
Earlier government reports and nuclear energy profiles list Lambapur–Peddagattu as a project in Nalgonda district of Andhra Pradesh and Domiasiat as a large uranium deposit in Meghalaya. Many exam guidebooks use this exact question and key, reinforcing the pairing of Andhra Pradesh and Meghalaya. Even though Nalgonda is now part of Telangana, the classic formulation in older questions still uses Andhra Pradesh as the answer, which is what this question expects.

Why Other Options Are Wrong:
Jharkhand and Arunachal Pradesh: Jharkhand does host uranium mining at Jaduguda, but Lambapur is not located there, and Domiasiat is not in Arunachal Pradesh.

West Bengal and Assam: These states do not correspond to the named deposits in standard references.
Maharashtra and Sikkim: Neither state is associated with Lambapur or Domiasiat uranium mines in exam-oriented GK.
Telangana and Meghalaya: This pairing reflects the current political reality for Lambapur, but the traditional and expected exam answer is given in terms of the earlier state, Andhra Pradesh.

Common Pitfalls:
Students may become confused by the creation of Telangana and be unsure whether the answer should mention Andhra Pradesh or Telangana. Since many exam questions were framed before Telangana was carved out, they still expect the original pairing of Andhra Pradesh and Meghalaya. A good strategy is to remember both facts: geographically, Lambapur lies in today's Telangana, but in older GK questions it is associated with Andhra Pradesh.

Final Answer:
Andhra Pradesh and Meghalaya
