(b) the random error due to using the chance to select a sample.

(c) any error due to practical difficulties such as contacting the subjects selected.

(d) any systematic error that tends to occur in the same direction whenever you use this sampling method.

(e) racism or sexism on the part of those who take the sample.

Short answer

The correct option is (c) any error due to practical difficulties such as contacting the subjects selected.

Step-by-step solution

Given information

sampling bias is likely to occur when some subjects of the population are more often chosen in comparison to other subjects.

Concept

Individuals are purposely subjected to a treatment in order to measure their responses in an experiment.

Explanation

When some individuals of the population are picked more frequently than others in an experiment, sampling bias is likely to emerge. As a result, bias in a method can be attributed mostly to the subjects or individuals chosen. As a result, the best solution is (c).
