The correct answer is C "first put the specimen into focus with a low power lens, then switch to a high power lens"

The low power lens allows a broad spectrum view of the specimen, allowing the user to zoom into a place of interest in switching to a high power lens. This is the same way you would locate a point of interest if using binoculars; first you spot something of interest with your eyes (low power lens), then you switch to your binoculars (high power lens) for a closer look.
