Correct Answer: Option B
Explanation

Aluminum is ideal as an alloy for aircraft because it strikes a great balance between being lightweight, strong, resistant to corrosion, and relatively easy to work with, making it perfect for building large aircraft structures while minimizing overall weight, which significantly improves fuel efficiency and performance; this is especially important due to its high strength-to-weight ratio compared to other metals like steel.
