Answer

Explanation:

Step1: Analyze statement I

The two cities with the highest number of respondents are Carsonville (471) and Appleton (463). In Carsonville, 266 support candidate B and 205 support candidate A. In Appleton, 260 support candidate A and 203 support candidate B. So, not both cities show more support for candidate A. Statement I is false.

Step2: Analyze statement II

The number of people who support candidate B in Carsonville is 266, and in New Thomas is 138. $266\neq2\times138$. Statement II is false.

Step3: Analyze statement III

The number of residents of Center - City who responded is 350, and from New Thomas is 318. Since $350>318$, more residents of Center City responded to the poll than the number who responded from New Thomas. Statement III is true.

Step4: Analyze statement IV

The total number of people who support candidate A is 797, and for candidate B is 805. So, more residents support candidate B than candidate A. Statement IV is false.

Answer:

B. III only
