The answer is B
Step-by-step explanation:
Definition of margin of error is simply expected error from result of a survey. Which means the actual vote results are in the range of plus or minus %3.
On this survey the result is %55 percent in favor of Taylor and the margin of error is %3. That means in the real election Taylor will get votes in between %52-%58. In other word
The sample proportion minus the margin of error is greater than 0.50, which provides evidence that more than half of all likely voters plan to vote for candidate Taylor.
