Task: Answer the multiple-choice question.
Query: Which compound exhibits a 8.599\% 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, c, or d without using any other words.
Options:
[a] O=C(CSc1nnnn1-c1ccc2c(c1)OCO2)NCc1cccs1
[b] COc1ccc(OC)c(-n2c(-c3ccc(C)cc3)n[nH]c2=S)c1
[c] CNC(=O)CN(c1cccc2ccccc12)S(C)(=O)=O
[d] COc1cc(C(=O)O)c2c(c1C)OC(=O)c1c(C)cc(O)c(C=O)c1O2
Answer: c. CNC(=O)CN(c1cccc2ccccc12)S(C)(=O)=O
