At which of the following places did Prachi Yadav win gold medal?

The correct answer is (A) 0.04 to 0.12 kcal/m·hr·°C.

• Thermal Conductivity of Wood: Wood is a natural thermal insulator. Its thermal conductivity typically ranges between $0.04$$\text{ to }$0.12$\text{ kcal/m}$$\cdot$$\text{hr}$$\cdot$^$\circ$$\text{C}$ ($0.1$$\text{ to }$0.3$\text{ W/m}$$\cdot$$\text{K}$) depending on moisture content and wood density.
