To calculate the MAD (Mean Absolute Deviation), we need to find the absolute difference between each data point and the mean, and then take the average of those absolute differences. 
Mean = (2+4+6+8+10)/5 = 6
Absolute differences from the mean: 
|2-6| = 4
|4-6| = 2
|6-6| = 0
|8-6| = 2
|10-6| = 4
Average of absolute differences = (4+2+0+2+4)/5 = 2.4
Therefore, the MAD is 2.4, which is closest to option B) 1.6667.
