To calculate the mean absolute deviation, we first need to find the mean of the given data. 
Mean = (120+150+100+80+200+90+60+70+110+140)/10 = 109

Next, we need to find the absolute deviation of each data point from the mean. 
Absolute deviations: 
|120-109| = 11 
|150-109| = 41 
|100-109| = 9 
|80-109| = 29 
|200-109| = 91 
|90-109| = 19 
|60-109| = 49 
|70-109| = 39 
|110-109| = 1 
|140-109| = 31

Now, we take the average of the absolute deviations: 
Mean absolute deviation = (11+41+9+29+91+19+49+39+1+31)/10 = 21.67

Therefore, the answer is C) 21.67.
