Task: Answer the multiple-choice question.
Question: Which drug has a 19.446% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) CCCCN(C(C)=O)c1c(N)n(CCC)c(=O)n(CC(=O)Nc2cc(Cl)cc(Cl)c2)c1=O
(b) CCC(C)c1c(O)nc(SCC(=O)Nc2ccccc2)[nH]c1=O
(c) O=S(=O)(Nc1ccncc1Cl)c1cccc(Cl)c1Cl
Answer: c. O=S(=O)(Nc1ccncc1Cl)c1cccc(Cl)c1Cl
