Explanation / Answer

It can be seen from the output of three models provided that Adjusted R Square and Root MSE are as follows;

Model

Adjusted R Square

Root MSE

0.7533

0.43068

0.1093

0.8183

0.6075

0.54319

From this table it is observed that for Model A, Adjusted R Square is more than that in other two models.

Further Root MSE of Model A is lesser than that in other two models.

Hence it is convenient to select Model A rather than Model B or Model C.
