Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.895\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) COc1ccc(-c2noc(-c3ccc(Br)o3)n2)cc1
(b) CCCCOc1ccc(/C=C/C(=O)OCC(=O)NC(=O)NCC(C)C)cc1OCC
(c) O=S(=O)(c1ccc(Cl)nc1)N1CCN(Cc2ccc3c(c2)OCO3)CC1
(d) CSc1ccc(/C=N\NC(=O)CC(=O)NC(C)C)cc1
(e) O=S(=O)(/N=C(/Nc1ccccc1F)c1ccccc1)c1ccccc1
Answer: a. COc1ccc(-c2noc(-c3ccc(Br)o3)n2)cc1
