Task: Answer the multiple-choice question.
Query: Which drug exhibits a 18.738\% 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(Nc1cccc(F)c1)C1CCCCC1
[b] Cc1cccc(C(C(=O)NC2CCCC2)N(C(=O)c2csnn2)C2CCCC2)c1
[c] CCn1c(=O)c(C(=O)Nc2ccccc2S(N)(=O)=O)c(O)c2ccccc21
Answer: c. CCn1c(=O)c(C(=O)Nc2ccccc2S(N)(=O)=O)c(O)c2ccccc21
