Emily wants to find out if the carpool line around her school causes too much traffic on neighborhood roads.The valid sample of the survey is

As the problem is faced by the one of the member of the school , and most of the members would nod this.

As, teacher being the most respected person in that colony, and if they are honest ,

The survey of 25 teachers at the school , will give the best possible result.

But,the better result is given by, 25 members located around that area, because if there is a problem with carpooling, most of the members around that area will be mostly affected by this.And the best solution is to take their  opinion.

So, Option (B)  25 families living near the school , looks best options among the given option provided.
