Explanation

Correct answer is option A. Dendral, Mycin, PXDES and CaDet are different expert systems used for different purposes.

  • Dendral: It was an artificial intelligence based expert system used for chemical analysis. It uses a substance’s spectrographic data to predict its molecular structure.

  • Mycin: One of the earliest expert systems based on backward chaining. It can identify various bacteria that can cause severe infections and can also recommend drugs based on the person’s weight.

  • PXDES: It could easily determine the type and the degree of lung cancer in a patient based on the data.

  • CaDet: It is a clinical support system that could identify cancer in its early stages in patients.
