Correct answer is (A) basic pavement markings.
Explanation: Crosswalks are one of four types of basic pavement markings. There are four kinds of crosswalks: controlled and uncontrolled, marked and unmarked. Controlled crosswalks depend on a traffic signal, yield signs or a stop sign, to require motorists to stop for pedestrians. STOP-controlled crosswalks have STOP signs that require vehicles to stop prior to entering the crosswalk.
