Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.770\% 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] COc1cccc(OCCn2cc(C=O)c3ccccc32)c1
[b] O=C(COc1ncnc2ccccc12)NCCc1ccc(F)cc1
[c] O=C(CCC1CCCN(C(=O)c2cc(C3CC3)[nH]n2)C1)N1CCN(c2ccccn2)CC1
Answer: b. O=C(COc1ncnc2ccccc12)NCCc1ccc(F)cc1
