Task: Answer the multiple-choice question.
Query: Which drug has a 4.317\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CN(C)S(=O)(=O)N(CC(=O)N1CCN(c2ccccc2F)CC1)c1ccccc1
(b) CC1=C([N+](=O)[O-])C(c2ccccc2)NC(=O)N1
(c) CCOC(=O)C(C)Oc1ccc(C2NC(=O)NC(C)=C2C(C)=O)cc1Br
(d) COC(=O)CSc1nc(C2CC2)nc2ccccc12
Answer: c. CCOC(=O)C(C)Oc1ccc(C2NC(=O)NC(C)=C2C(C)=O)cc1Br
