A problem requires finding the number of cars on a dealer's lot. Which would not be a reasonable answer? Justify your response. \( \begin{array}{lll}\text { A. } 0 & \text { B. } 6 & \text { C. } 1 \\ \text { D. } 6 \frac{1}{2}\end{array} \) A. 0 ; there cannot be a zero number of cars. B. 6 ; there cannot be an even number of cars. C. 1 ; there cannot be an odd number of cars. D. \( 6 \frac{1}{2} \); there cannot be a fractional number of cars.
