Task: Answer the multiple choice question.
Query: Which compound has a 7.845\% 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 Cn1cccc1/C=N/NC(=O)c1cc2ccccc2cc1O
b CC1CCc2c(sc(/N=C/c3ccco3)c2C(N)=O)C1
c COc1ccc(S(=O)(=O)Nc2ccccc2C(=O)N2CCOCC2)cc1OC
d O=C(CCC(=O)c1cccs1)NCCCN1CCCC1=O
Answer: c. COc1ccc(S(=O)(=O)Nc2ccccc2C(=O)N2CCOCC2)cc1OC
