In a survey of high school students, 35 percent admitted to having lied to their parents at least once in the past month. However, the survey may underestimate the percentage of high school students who lie to their parents because _____________.

at least once means = Once , twice , thrice ...

Which of the following best completes the passage above?

(B) some students who claimed on the survey to have lied to their parents only once might have actually lied to their parents many more times in the past month

The passage talks about telling lie at least once ( hence it can be safely be presumed that it includes students telling lies more than once ) , this statement merely repeats what is already given in the passage in different words and no additional information is provided to carry forward the discussion.

Even if the students lied more than once it doesn't underestimate the survey ( Because we considered - At least once and included in the group students who lied more than once)

(D) some dishonest students taking the survey might have claimed on the survey to be honest

If the same group of dishonest students who lied to their parents ( At least once ) provided incorrect statement in the survey then it will clearly affect the results of the survey...
