Task: Answer the multiple choice question.
Question: Which drug has a 2.906\% 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) CC1=C(C(=O)OCc2ccccc2)C(c2cccc3ccccc23)NC(=O)N1CCCC(=O)O
(b) COC(=O)/C(=N/Nc1ccccc1OC)N1CCCc2ccccc21
(c) COc1ccc(Cc2nnc3sc(SCC(=O)Nc4ccccc4)nn3c2=O)cc1OC
(d) O=C(CCCNS(=O)(=O)c1ccc(Br)cc1)N1CC[C@@]2(O)CCCC[C@H]2C1
Answer: c. COc1ccc(Cc2nnc3sc(SCC(=O)Nc4ccccc4)nn3c2=O)cc1OC
