Task: Answer the multiple choice question.
Question: Which drug exhibits a -53.551% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1cccc(OC)c1OCCNCC1CSc2ccccc2O1.Cl
b O=C(CCn1c(=O)oc2ccccc21)NCCCN1CCOCC1
c COc1cc2c(cc1NC(=O)CN1CCN(S(=O)(=O)c3ccc(C)cc3)CC1)oc1ccccc12
d Cc1c(C(=O)N2CCN(c3ccc([N+](=O)[O-])cc3)CC2)oc2ccccc12
Answer: a. COc1cccc(OC)c1OCCNCC1CSc2ccccc2O1.Cl
