Task: Answer the multiple-choice question.
Query: Which compound has a 13.346\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a COCCN(C(=S)Nc1cccc(C)c1)C(C)c1cccs1
b CN(Cc1nc2ccccc2n1C)C(=O)c1cccs1
c O=C(COC(=O)CN1C(=O)C2CCCCC2C1=O)NCc1ccc(Cl)cc1Cl
d O=C(NCC1CC1)c1cc(-c2ccccc2)nn1CC1CC(c2cccc([N+](=O)[O-])c2)=NO1
Answer: a. COCCN(C(=S)Nc1cccc(C)c1)C(C)c1cccs1
