Extrapyramidal symptoms are common side effects of
a. anti-psychotic drugs
b. anti-depressant drugs
c. anti-manic drugs
d. anti-convulsant drugs

The answer is:  [A]:  anti-psychotic drugs .

   (which are sometimes prescribed for "mania", or "manic-depression"; and even have FDA-approval for treatment of "manic-depression"; known as: "bipolar disorder" — even in bipolar disorder without psychotic features;  and even have FDA-approval for treatment-resistant major (unipolar) depression combined with an SSRI (selective serotonin reuptake inhibitor); even in cases of major depression without psychotic features.  Fortunately, the so-called "atypical anti-psychotics"; or, "newer generation antipsychotics", tend to have a lesser risk of such side effects.).
