Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.620\% human ether-à-go-go related gene (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 additional words.
Options:
a COc1ccc(C(=O)NC(=S)NCc2ccccc2)cc1OC
b CCCCOC(=O)C1=C(C)Nc2nnnn2C1c1ccccc1Cl
c Cc1c(NC(=O)COC(=O)C2(c3ccccc3F)CCCC2)c(=O)n(-c2ccccc2)n1C
