We are given that $78\%$of all students at a particular college get financial aid. From random sample of$100$students $72\%$respondents get financial statement.

We need to find out correct option from given options.

All persons about whom we want to collect data are included in the population.
A sample is a subset of the population from which data is collected.
The sample in our question is the$100$ students in the random sample, whereas the population is defined as all students at a specific college.
A parameter is population descriptive measure, whereas a statistic is sample descriptive measure.
The $72\%$is based on a random sample of all students, hence$72\%$ is a statistic.
The $78\%$is based on all students at a specific college, hence it is based on the population, implying that $78\%$is a parameter.

From all above information we get conclusion that option c in correct option which states that $78\%$is a parameter and $72\%$is a statistic.
