Answer to Question 1

C
Clozapine's wider range of action may be the result of the medication's effects on dopamine receptors D1 and D4 and several other transmitters. In addition, clozapine blocks dopamine receptor D2, which all other antipsychotics block as well. Illnesses such as schizophrenia (and perhaps other psychoses) involve excessive activation of dopamine receptor D2, and antipsychotics seek to alleviate the illness by blocking such activation.

Answer to Question 2

C
