Task: Answer the multiple-choice question.
Question: Which drug has a -18.184\% 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] CCOC(=O)/C(C(=O)Nc1ccc(Cl)cc1Cl)=C1/NC(C)(C)Cc2ccccc21
[b] C=CCNC(=O)c1ccc(-c2ccc([N+](=O)[O-])cc2)o1
[c] Cn1c(OCc2cccnc2)nc2c1c(=O)n(Cc1ccc(Cl)cc1)c(=O)n2C
Answer: b. C=CCNC(=O)c1ccc(-c2ccc([N+](=O)[O-])cc2)o1
