Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 18.998\% 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 additional words.
Options:
(a) O=C(CCC(=O)OCC(F)(F)C(F)F)Nc1ccccc1F
(b) COC(C(=O)Nc1ccc(Br)cc1F)c1ccccc1
(c) COc1ccc(-c2noc(CSc3nnc(CCc4ccccc4)n3-c3ccccc3)n2)cc1OC
(d) COc1cccc(-c2noc(CCCC(=O)N3CCOCC3)n2)c1
(e) Cc1c(Cl)c([N+](=O)[O-])nn1CCCC(=O)Nc1cccc(Cl)c1
Answer: a. O=C(CCC(=O)OCC(F)(F)C(F)F)Nc1ccccc1F
