All of the following are uses of aluminum EXCEPT:
Correct answer: D. It is very heavy metal and used to make balance
- A. It is used in the manufacture of buses, trains and aeroplanes
- B. It is used in making of utensils and window frames
- C. It is used in thermite welding
- D. It is very heavy metal and used to make balance
Explanation
The correct answer is Option D. Aluminum is known for being a lightweight metal, not a heavy one. This makes it unsuitable for making balances, as balances require heavy materials for accuracy. The other options correctly highlight the various uses of aluminum in different industries.
