Question

Materials which can be drawn into wires are called ductile. Which of the following is not a ductile material?

• A. Silver
• B. Copper
• C. Sulfur
• D. Aluminum

Answer 1

The correct option is C

Sulfur

Explanation for correct answer

Option (C) Sulfur

1. Materials which can be drawn into thin wires is called as ductile material. Sulfur is brittle because Sulfur is non-metal and cannot be drawn into thin wires.
2. Hence, option (C) is correct.

Explanation for incorrect answer

(A) Silver

1. Silver is a metal, so it can be easily drawn into wires and considered as Ductile.
2. Hence option (B) is incorrect.

(B) Copper

1. Copper is a metal and are used to make thin wires because of this it is considered as Ductile.
2. Hence option (B) is incorrect.

(D) Aluminum

1. Aluminum is used in making steel appliances because of its ductile character.
2. Hence Option (C) is incorrect.

Therefore, Sulfur is not considered as ductile material because of its non-metallic character. Hence, Option (C) is incorrect.
