Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.049% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a c1cncc(-c2nc(NCCCn3ccnc3)c3ccccc3n2)c1
b O=c1oc(-c2ccc([N+](=O)[O-])cc2)nc2ccc(O)cc12
c Cc1ncc(CO)c2cc(C(=O)Nc3ccccc3Cl)c(=Nc3cccc(C(N)=O)c3)oc12
Answer: b. O=c1oc(-c2ccc([N+](=O)[O-])cc2)nc2ccc(O)cc12
