Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.091% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COCCCNC(=O)C12CCC(C)(C(=O)C1)C2(C)C
[b] C=CCc1cccc(/C=N/NC(=O)c2cc([N+](=O)[O-])nn2Cc2ccccc2)c1O
[c] C/C(=N\NC(N)=O)c1cc(Cl)cc(Cl)c1O
Answer: b. C=CCc1cccc(/C=N/NC(=O)c2cc([N+](=O)[O-])nn2Cc2ccccc2)c1O
