Task: Answer the multiple-choice question.
Question: Which compound has a 0.424\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a O=C(Cn1cnc2c(cnn2-c2ccccc2)c1=O)NCc1ccccc1
b CCCC(=O)n1nc(NCc2ccc(OC)cc2)nc1NCc1ccc(OC)cc1
c Cl.Nc1c(Br)cc(Br)cc1CNC1CCC(O)CC1
d COC(=O)/C(=C\Nc1ccc(OC)cc1)NC(=O)c1ccc(Cl)cc1Cl
e CCOC(=O)N/N=C/c1ccccc1F
Answer: a. O=C(Cn1cnc2c(cnn2-c2ccccc2)c1=O)NCc1ccccc1
