Transmission line connects

(A) Generating station to a switching station/step-down transformer station.

(B) Step-down transformer station to service transformer banks.

(C) Distribution transformer to consumer premises. 

(D) Service points to consumer premises.

Answer: (A) Generating station to a switching station/step-down transformer station.

Explanation:

the transmission line connects the generating station to a switching station or a step-down transformer station, which is a common application of transmission lines. The high-voltage power generated at the generating station is transmitted over long distances to the switching station or step-down transformer station, where it is stepped down to a lower voltage level for further distribution.
