Task: Answer the multiple choice question.
Question: Which compound exhibits a 6.438\% 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.) O=C(COc1ccccc1F)NC12CC3CC(CC(C3)C1)C2
b.) O=c1cc(CSc2ccc(Cl)cc2)nc(-c2ccncc2)[nH]1
c.) CCC(c1nc2ccccc2c(=O)n1-c1cccnc1)N1C(=O)c2ccccc2C1=O
d.) COc1ccc(CN2C(=O)c3cccnc3C2=O)cc1S(=O)(=O)N1CCCCC1C
Answer: c. CCC(c1nc2ccccc2c(=O)n1-c1cccnc1)N1C(=O)c2ccccc2C1=O
