Question

multiple choice question in what type of plate is the sample spread over the surface of the medium using an inoculating loop, as shown in this figure? options: a blank plate, a spread plate, a pour plate

Explanation:

A spread plate is prepared by spreading a sample (usually a liquid culture or a diluted sample) over the surface of an agar plate using an inoculating loop. A blank plate has no sample, and a pour plate involves mixing the sample with molten agar before pouring it into the plate. So the correct type here is a spread plate.

Answer:

B. a spread plate (assuming the options are labeled with A, B, C where B is "a spread plate" as per typical multiple - choice formatting for this question context)
