Which one of the following is NOT correctly matched? Aluminium Plants Location

1. A

   Madras Aluminium - Chennai Company Limited (MALCO)

   Madras Aluminium Company Limited (MALCO) claims Chennai as its location. This option is the official key because MALCO's plant is actually situated at Mettur in Tamil Nadu, not Chennai, making this pair incorrectly matched.

2. B

   Bharat Aluminium - Korba Company Limited (BALCO)

   Bharat Aluminium Company Limited (BALCO) claims Korba as its location. This pair is correctly matched as BALCO's major aluminium plant is located in Korba, Chhattisgarh.

3. C

   Hindustan Aluminium - Renukoot Corporation Limited (HINDALCO)

   Hindustan Aluminium Corporation Limited (HINDALCO) claims Renukoot as its location. This pair is correctly matched since HINDALCO operates its prominent production facility in Renukoot, Uttar Pradesh.

4. D

   Indian Aluminium - Hirakud Company Limited (INDAL)

   Indian Aluminium Company Limited (INDAL) claims Hirakud as its location. This pair is correctly matched because INDAL established an important aluminium smelting unit at Hirakud in Odisha.

Summary. Official key is (a) because Madras Aluminium Company Limited (MALCO) is located at Mettur, not Chennai. The other three pairs—BALCO at Korba, HINDALCO at Renukoot, and INDAL at Hirakud—are all correctly matched locations of major Indian aluminium plants. Aspirants often confuse corporate headquarters with the actual manufacturing plant sites. Careful verification of plant locations resolves such mapping questions easily. Thus, option (a) stands out as the only incorrect match among the given choices.
