Based on the described scenario, the correct conclusion about Block A is:
**B: It is a poor conductor of heat.**
Here's the reasoning:
- When Block A was placed on top of the hot metal block, if Block A was a good conductor of heat, it would have quickly absorbed the heat from the hot metal block, and its temperature would rise significantly upon touching it.
- Since Block A remained at room temperature even after being in contact with it for five minutes, it suggests that Block A does not effectively conduct heat.
The other options can be assessed as follows:
- **A: It is a good conductor of heat** - This is incorrect based on the observation.
- **C: It is a good conductor of electricity** - We cannot conclude anything about its electrical conductivity based solely on the heat conduction observation.
- **D: It is made of ferrous material and is magnetic** - There is no information to support the claim regarding the magnetic properties of Block A.
Thus, the most appropriate conclusion is that Block A is a poor conductor of heat.
**B: It is a poor conductor of heat.**
