Task: Answer the multiple-choice question.
Question: Which drug has a 0.720\% 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] CC1(OC(=O)C2CCCC2)C(=O)C=C2C=C(c3ccsc3)N(Cc3ccco3)C=C2C1=O
[b] O=C(CCc1nc2ccccc2c(=O)[nH]1)N1CCN(S(=O)(=O)c2ccccc2Br)CC1
[c] O=S(=O)(c1cccc(-c2nc3n(n2)Cc2ccccc2-3)c1)N1CCCCC1
Answer: a. CC1(OC(=O)C2CCCC2)C(=O)C=C2C=C(c3ccsc3)N(Cc3ccco3)C=C2C1=O
