To ensure that a sample represents a target population, researchers select
a.
people at random from the target population.
b.
a large number of people from one subgroup.
c.
a slightly larger percentage of people from certain subgroups.
d.
all of the above.

The target population is the whole population, or group, that a researcher is curious about researching and analyzing. A sampling frame is then chosen from this target population.

The target population is the subset of individuals for whom the program is planned, that you will actively enter and hold, and for whom you will hold yourselves responsible for achieving the final result.

A sample is the group of individuals who make an effort in the investigation. The people who take part are mentioned as “participants”. When definite groups are over or underrepresented within the sample taken.

Therefore, a large number of people from one subgroup represents the target population.

Hence, option B is correct.
