Final answer:

AC is preferred for power transmission due to its ease of voltage transformation using transformers, reducing energy loss during transmission.


Explanation:

Alternating current (AC) is used for power transmission to buildings primarily because it can be easily transformed to higher or lower voltages using transformers, reducing energy loss during transmission. In contrast, changing the voltage of direct current (DC) is more challenging and leads to higher power losses.
