Task: Answer the multiple choice question.
Query: Which compound exhibits a -18.118\% 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) O=S(=O)(NCCC1=CCCCC1)c1ccc(OC(F)(F)F)cc1
(b) COc1cc(C(=O)COC(=O)Cc2cnc3sccn23)cc(OC)c1OC
(c) COc1ccccc1OC(C)C(=O)Nc1ccc(S(=O)(=O)N2CCN(C)CC2)cc1
(d) CCCNC(=O)c1cc(Cl)c(NC(=O)C2=C(C)OCCS2)cc1OC
Answer: a. O=S(=O)(NCCC1=CCCCC1)c1ccc(OC(F)(F)F)cc1
