Brinell Hardness Number (BHN) for talc is approximately in the range of

Answer: Option A

Brinell Hardness Number (BHN) is a measure of the hardness of materials, with higher values indicating harder materials.

Talc is a soft mineral, often used in cosmetics and as a lubricant.

The BHN of talc is very low, typically falling within the range of 1-5, indicating its softness compared to other materials.
