Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.817\% 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 CC(C(=O)N1CCc2ccccc2C1)N1C(=O)c2ccccc2C1=O
b C=CCSc1nnc2c(n1)[nH]c1c(C)cccc12
c O=C(CSc1ncccc1C(=O)O)Nc1ccc2c(c1)OCCO2
d Cc1ccc(NC(=O)c2oc3ccccc3c2C)nc1
Answer: a. CC(C(=O)N1CCc2ccccc2C1)N1C(=O)c2ccccc2C1=O
