(c) A cluster sample

Step-by-step explanation:

A cluster sample occurs when the intended population is divided into non - overlapping sub - groups or clusters and some of these clusters are represented in the sample.

From the question, In a state 15 high schools where randomly selected and the standardized test was administered to only 10th grade student. Here, the high schools are the non-overlapping sub groups that is randomly selected and a reasonable representation of the entire subgroups.
