Problem statement: Answer the multiple-choice question.
Query: Which drug has a -1.971\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) O=C(CSc1nnc(-c2ccc([N+](=O)[O-])cc2)o1)Nc1ccccn1
b.) O=C(CC1SCCNC1=O)Nc1ccccc1Cl
c.) O=C(CCN1C(=O)/C(=C\c2ccccc2)SC1=S)NNC(=O)c1ccccc1O
d.) O=c1cc(O)nc(SCc2ccc(Cl)cc2)[nH]1
Answer: d. O=c1cc(O)nc(SCc2ccc(Cl)cc2)[nH]1
