A measure of dispersion quantifies how spread out the data is. The mean squared deviation is a measure of how much on average the data points differ from the mean, and thus is a measure of dispersion. The other options are either measures of central tendency (A, D, E) or a measure of the most frequently occurring value (C), and do not capture how spread out the data is.
