Task: Answer the multiple-choice question.
Query: Which drug has a -50.087% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=[N+]([O-])c1ccc(Nc2cccc(F)c2)nc1
b S=C1NC2=C(C(c3ccc(Br)cc3)N1)N1CCC2CC1
c CCOC(=O)c1c(NC(=O)CSc2nnc(CNC(=O)c3ccco3)n2C)sc2c1CCC2
d N/C(CN1CCCC1=O)=N\OC(=O)c1ccccc1Cl
Answer: c. CCOC(=O)c1c(NC(=O)CSc2nnc(CNC(=O)c3ccco3)n2C)sc2c1CCC2
