Task: Answer the multiple choice question.
Question: Which drug exhibits a -15.279\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) COc1cc(C#N)ccc1OCC(=O)Nc1cccc(S(=O)(=O)N2CCCC2)c1
(b) O=C(COc1ccc(Cl)cc1)NCc1cn2cc(Cl)ccc2n1
(c) O=C(Nc1nnc(C2=COCCO2)o1)c1ccc(Br)cc1
(d) CC(Sc1nnnn1C)C(=O)NC(=O)NC1CCCCC1
Answer: b. O=C(COc1ccc(Cl)cc1)NCc1cn2cc(Cl)ccc2n1
