all of the following are advantages of using aluminum except:
a) durability.
b) reduced weight.
c) easy to repair.
d) corrosion resistance.

Explanation:

To solve this, we analyze the properties of aluminum:

• Durability: Aluminum is durable, so A is an advantage.
• Reduced weight: Aluminum is lightweight, so B is an advantage.
• Easy to repair: Aluminum is not easy to repair (e.g., welding aluminum is more complex than some materials), so C is not an advantage.
• Corrosion resistance: Aluminum has good corrosion resistance (forms an oxide layer), so D is an advantage.

Answer:

C) Easy to repair
