Final answer:
option a.Physical landforms have a profound impact on where people live due to their influence on agricultural practices, climate conditions, and access to water resources, shaping the distribution of settlements and societal development.
Step-by-step explanation:
Physical landforms significantly influence why people choose to live where they do throughout the world. These landforms affect such aspects as agricultural practices, as the type of soil and landscape determine what crops can be grown, and whether the land is suitable for subsistence or commercial agriculture.
Climate conditions are also determined by landforms, which can dictate the overall weather patterns and growing seasons. Furthermore, physical features such as rivers and lakes provide essential access to water resources for drinking, irrigation, and transportation. Overall, these factors contribute to the economic, social, and cultural development of a place, influencing the distribution of settlements and how societies adapt to and modify their environment.
