Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Hornblende.
Hornblende is an inosilicate amphibole mineral that is known for its durability and strength, making it ideal for construction purposes.
Its resistance to weathering and ability to withstand heavy loads contribute to its use in road and railway infrastructure. Additionally, its dark color and non-slip surface make it suitable for applications where traction is important, such as in ballast for railroads.
