Task: Answer the multiple-choice question.
Query: Which compound exhibits a 14.731\% 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 other words.
Options:
a COc1nc(-c2ccccc2)cc(-c2ccccc2)n1
b O=C(Nc1ccc(Cl)cn1)c1cc2ccccc2o1
c CCNC(=O)Cn1cnc2c1c(=O)n(C)c(=O)n2C
d COC(=O)c1nc(-c2ccc(C)cc2)oc1N(C)C
e COc1ccc(C(NC(=O)/C=C\c2ccco2)c2ccc(OC)c(OC)c2)cc1
Answer: c. CCNC(=O)Cn1cnc2c1c(=O)n(C)c(=O)n2C
