C)symmetrical. 
D)none of the above

The boxplot shows that the median number of hours is around 7.5 and the majority of the batteries lasted between 5 and 10 hours. However, there are some batteries that lasted for a very long time (outliers). This indicates that the distribution is skewed to the right, as there are some values that are much larger than the rest of the data. Therefore, option A, right-skewed, is the best choice.
