Task: Answer the multiple choice question.
Question: Which drug has a -24.856% 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) CCc1ncc(C)[nH]1
(b) O=C(c1cc(S(=O)(=O)N2CCCCC2)ccc1Cl)N1CCOCC1
(c) CCCCN(CC)c1nc(N)c(C#N)c(CC#N)c1C#N
Answer: c. CCCCN(CC)c1nc(N)c(C#N)c(CC#N)c1C#N
