• D. Through government policies only.

Answer: (A)

The spread of world religions happens through active, connected processes that move beliefs along with people, ideas, and institutions. Trade routes, conquests, migrations, and missionary work provide concrete pathways for diffusion. Merchants, travelers, and traders carry religious ideas as they encounter new regions, making ideas travel farther and faster than would happen by chance alone. Empires and military campaigns often establish administrative centers and networks where rulers promote or enforce religious practices, expanding their influence. When people move—whether seeking work, resettling after displacement, or forming new communities—they carry their beliefs with them, introducing them into new cultural landscapes. Missionary efforts intentionally spread religious teachings, often establishing schools, churches, mosques, or temples that help convert and educate new adherents.

In contrast, climate patterns don’t function as a diffusion mechanism, and random chance alone doesn’t reliably explain how beliefs become widely adopted. Government policies can influence religion, but they don’t by themselves account for the broad, patterned spread that these other factors produce.
