Task: Answer the multiple choice question.
Question: Which compound has a 13.124\% 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 O=C(CCn1c(=O)[nH]c2ccsc2c1=O)N1CC(=O)N(CCc2ccccc2)C(=O)C1
b CCOC(=O)c1cc(NC(=O)COc2ccc([N+](=O)[O-])cc2)cc(C(=O)OCC)c1
c Cc1ccc(N)c(C(=O)CCCCC(=O)O)c1
d CC(C)=CCc1c(C)nc2ccccc2c1C(=O)O
Answer: d. CC(C)=CCc1c(C)nc2ccccc2c1C(=O)O
