Question

What is one of the drawbacks of an Internet-based survey?

Answer 1

Those who do not have access to the internet can't take the survey. The data is also less secure. 

Answer 2

C. Only those interested in your field will respond.

Step-by-step explanation:

The following options are missing:

A. The participants have no confidentiality.

B. It doesn't reach a wide number of people.

C. Only those interested in your field will respond.

D. It has a slow turnaround for responses.

In an internet-based survey, people who received the survey may not answer it. On the other hand, the other options are incorrect, that is, surveys can be answered without given personal information, i.e. they are confidential; because they are internet based, they reach almost everybody; and the answers are collected immediately.
