Task: Answer the multiple choice question.
Question: Which compound exhibits a -0.073\% 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, or c without using any additional words.
Options:
a CN1CCC2(O)OCCCC2C1
b CCCCCCn1c(O)c(C=NCCCn2ccnc2)c(=O)[nH]c1=O
c Cc1ccc(NC(=O)C2COc3ccccc3O2)cc1S(=O)(=O)N1CCOCC1
Answer: b. CCCCCCn1c(O)c(C=NCCCn2ccnc2)c(=O)[nH]c1=O
