The scale of measurement and the shape of the distribution are important factors in determining which measure of central tendency to use. For nominal or categorical data, the mode is the only appropriate measure. For ordinal data, the median is usually used. For interval or ratio data, the mean is often used if the distribution is symmetric, and the median if the distribution is skewed. Therefore, D is the best choice as it deals with these factors.
