Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -0.522% 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 additional words.
Options:
[a] C=CCn1c(C)cc(C(=O)CSc2nc3ccccc3[nH]2)c1C
[b] O=C(Nc1ccc(N2CCN(C(=O)c3ccco3)CC2)c(Cl)c1)c1cc2ccccc2o1
[c] COc1cc(CN2CCN(C(=O)Cc3ccccc3)CC2)cc(OC)c1OC.O=C(O)C(=O)O
[d] Cc1cc(Nc2ccccc2F)nc(-c2ccccc2O)n1
Answer: c. COc1cc(CN2CCN(C(=O)Cc3ccccc3)CC2)cc(OC)c1OC.O=C(O)C(=O)O
