C. Set size="6" mobile-device-size="12"
D. Set size="12" medium-device-size="6"

正解：D

To display lightning-layout-items in one column on small devices and in two columns on larger devices, you should set the size attribute to "12" for small devices and the medium-device-size attribute to "6". This ensures that on small devices each item takes the full width, and on medium or larger devices, items take up half the width.References: Lightning Web Components Developer Guide - Layout Components
