A news graphic says a third-party candidate has 6% support with a plus or minus 4-point margin of error. Which reporting sentence is most accurate?

The candidate has exactly 6% support and cannot have more or less.
B
The margin of error proves the candidate is actually at 10%.
C

D
The candidate's support is estimated at 6%, but the plausible range is roughly 2% to 10%.
