Physical capital encompasses man-made production goods: machinery, tools, buildings, and infrastructure. Key attributes of physical capital include:
Tangibility: Physical capital is tangible, allowing for physical interaction and observation.
Tradability: Physical capital is generally tradable (can be bought or sold), though some infrastructure may have restricted trade. This is typically a characteristic.
Immobility: This is not a core feature. Physical capital, like machines, is often relocatable. Immobility is primarily linked to land (a natural resource), not physical capital.
Consequently, excluding immobility as a feature, option (B) (ii) and (iii) is logical. However, depending on context, the tradability aspect may be debated (in certain cases), potentially making (C) or (D) defensible based on interpretation.
