Il-1ß is a protein released by cells under conditions of infection. excessive release of il-1ß can be very damaging and can lead to severe disease. in a typical experiment, the typical concentration of il-1ß around stressed cells is 1100 ± 115 pg/ml. a researcher is testing drugs that can inhibit il-1ß release. she tests two drugs, drug-1 and drug-2, for their effects on il-1ß release. if the drugs have a z-score of -3, she will consider them promising for future study. in her experiment, stressed cells treated with drug-1 yielded 1469 pg/ml of il-1ß, while drug-2 yielded 777 pg/ml of il-1ß. is she going to continue studying either drug, and if so, which one?

a. she will continue studying drug-1 but not drug-2.
b. she will continue studying both drug-1 and drug-2.
c. she will continue studying drug-2 but not drug-1.
d. she will not study drug-2 or drug-1.
