Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.858\% 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 other words.
Options:
[a] O=C1C(C=NC2CC2)=C(O)c2ccccc21
[b] O=S(=O)(c1ccc(Br)cc1)c1nc(-c2ccccc2)oc1NCCN1CCOCC1
[c] COc1cc(CNn2c(C)n[nH]c2=S)cc(Cl)c1OCc1ccc(F)cc1
Answer: c. COc1cc(CNn2c(C)n[nH]c2=S)cc(Cl)c1OCc1ccc(F)cc1
