D Correct answer
Explanation

The accuracy of Configuration Interaction Theory calculations depends on the size of the molecule and the level of theory used. For small molecules, Configuration Interaction Theory can achieve chemical accuracy, while for larger molecules, it may only achieve semi-quantitative or qualitative accuracy.
