Problem statement: Answer the multiple-choice question.
Query: Which drug has a 5.744\% 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) COc1ccc(NC(=O)Cn2cnc3sc(C)c(S(=O)(=O)N4CCOCC4)c3c2=O)cc1Cl
(b) S=C1NC2=C(C(c3ccc(Br)cc3)N1)N1CCC2CC1
(c) CNC(=O)CC1C(=O)N(c2ccc(Cl)cc2)C(=S)N1NC(=O)c1cccc(F)c1
(d) O=C(Nc1cccc(Cl)c1)/C(=C\c1cccnc1)NC(=O)c1ccco1
Answer: a. COc1ccc(NC(=O)Cn2cnc3sc(C)c(S(=O)(=O)N4CCOCC4)c3c2=O)cc1Cl
