Option D is the correct option.
What is Mean Absolute Deviation?
'The mean absolute deviation (MAD) is the mean (average) distance between each data value and the mean of the data set.'
According to the given problem,
The mean height Variety A = 19 [ from the table ]
The mean height of variety B = 13 [ from the table ]
The spread is given by the mean absolute deviation, which 1.2 for Variety A and 2.4 for Variety B. So we can see that, the spread in Variety A is lesser than the spread in Variety B, which shows that the average height of Variety A varies less than the average height of Variety B.
We can see from the table that the average height of a variety A is indeed greater than that of Variety B. Also we can see that the Mean Absolute deviation of Variety A is 1.2 which is lesser than the Mean Absolute deviation of Variety B.
Hence, option D is correct since the average height of Variety A is greater than Variety B, and also the mean varies lesser in Variety A than in Variety B.
