To arrange the primary activities from oldest to newest, we need to understand the historical progression of human economic activities.
Based on the historical development of these activities, the correct order is: (C) Hunting and Gathering, (B) Nomadic Herding, (D) Primitive Subsistence Agriculture, (A) Extensive Commercial Grain Cultivation.
Hunting and gathering is considered the oldest primary activity, where humans relied on natural resources for sustenance. This activity involved hunting animals and gathering wild plants for food.
Following hunting and gathering, nomadic herding emerged as a primary activity. In this form of subsistence, humans raised livestock such as sheep, goats, and cattle, moving them seasonally to find grazing land.
Primitive subsistence agriculture came next, where early societies began cultivating crops for sustenance. This form of agriculture relied on simple tools and minimal technological advancement, with farmers growing crops in small quantities for personal use.
Extensive commercial grain cultivation, a more advanced form of agriculture, developed later. This type of agriculture involves large-scale cultivation of grains like wheat, maize, and rice, primarily for sale in global markets. It is characterized by the use of advanced technology and significant land areas.
These activities represent the evolution of human interaction with the environment, reflecting changes in technology, society, and economic practices over time.

Read the following passage and answer the question given below:
The clustered rural settlement is a compact or closely built-up area of houses. In this type of village, the general living area is distinct and separated from the surrounding farms, barns, and pastures. The closely built-up area and its intervening streets present some recognisable pattern or geometric shape, such as rectangular, radial, linear, etc. Such settlements are generally found in fertile alluvial plains and in the northeastern states. Sometimes, people live in compact villages for security or defence reasons, such as in the Bundelkhand region of central India and in Nagaland. In Rajasthan, scarcity of water has necessitated compact settlement for maximum utilisation of available water resources. Fragmented settlement types may result from segregation of a large compact village or from the tendency of clustering in a restricted area of dispersed settlements.
Dispersed or isolated settlement pattern in India appears in the form of isolated huts or hamlets of few huts in remote jungles, or on small hills with farms or pasture on the slopes. Extreme dispersion of settlement is often caused by the extremely fragmented nature of the terrain and land resource base of habitable areas. Many areas of Meghalaya, Uttarakhand, Himachal Pradesh, and Kerala have this type of settlement.
