According to what did African pastoralists change their movement?

Season and availability of fodder

The correct answer is A. African pastoralists commonly moved according to seasonal changes in rainfall, water sources, and the availability of grass or other fodder. During a dry period, they might travel toward places where water and grazing remained available; when rains returned, routes and grazing areas could change again. This flexible movement helped them use scattered resources without exhausting one location throughout the year. Option B is unrelated to pastoral ecology, option C has no connection with the movement of herds, and option D concerns maritime transport rather than land-based livestock management. The governing concept is seasonal mobility as an adaptation to changing environmental conditions.
