this is what i got- Scanning electron microscopes (SEM) are useful for studying the details of a specimen’s surface. The electron beam scans the specimen’s surface, which is coated with a thin layer of gold metal. The electrons that scatter off of the gold-coated surface are focused onto a screen, forming a detailed image of the specimen surface. The image is three-dimensional and black and white.

it's not A. The electron beam is scattered off the gold-coated surface, it doesn't pass through the specimen.

do you mean it's not B because B say it's passed not a?
