Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.571\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(CCSCCc1ccccn1)Nc1c(F)c(F)c(F)c(F)c1F
[b] Nc1c(-c2ccc(F)cc2)cnc2ncnn12
[c] O=C(Nc1nc2ccc(Cl)cc2s1)C1CCCO1
Answer: c. O=C(Nc1nc2ccc(Cl)cc2s1)C1CCCO1
