The practice of gathering generally involves collecting wild resources, such as fruits, nuts, and herbs. The statements are analyzed as follows:
- I. Generally gathering is practised in regions with harsh climatic conditions: This is true because gathering is often practiced in areas where agricultural activities are difficult, due to climate or terrain, such as in tropical forests or Arctic regions.
- II. In modern times, some gathering is market-oriented: This is also correct. In some regions, gathering has become a market-oriented activity, where people collect wild products like medicinal herbs, wild fruits, and mushrooms to sell in markets.
- III. Denmark is a classical example of gathering activities: This statement is incorrect. Denmark is not typically known for gathering activities as it is a highly developed country with a focus on agriculture and industrialization.
- IV. Gathering is practised mostly by primitive societies: This is correct. Traditionally, gathering was primarily practiced by hunter-gatherer societies, particularly before the advent of agriculture.
Thus, the correct option is (A), as statements I, II, and IV are correct.
