Task: Answer the multiple-choice question.
Question: Which compound exhibits a 16.760\% 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: CCc1nnc(NC(=O)c2ccc(OCc3c(C)noc3C)c(OC)c2)s1
b: N#C/C(=C/c1cc[nH]c1)C(N)=S
c: COc1ccc(CN2CCc3c([nH]c4ccccc34)C2)cc1Br
Answer: b. N#C/C(=C/c1cc[nH]c1)C(N)=S
