Task: Answer the multiple choice question.
Query: Which drug has a 0.289\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) Brc1ccccc1C1=Nn2c(nnc2-c2ccccc2)SC1
(b) CCOc1ccc(C(=O)Nc2ccc(N3CCCC3)cc2)cc1
(c) CCn1nnnc1SCC(=O)c1cc(Cl)ccc1OC
(d) CCCCNS(=O)(=O)c1ccc(OC)c(C)c1
(e) O=C(c1cc(-c2ccc3c(c2)OCO3)on1)N1CCN(c2ccccc2)CC1
Answer: c. CCn1nnnc1SCC(=O)c1cc(Cl)ccc1OC
