Task: Answer the multiple choice question.
Question: Which drug exhibits a -8.065\% 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(Nc1c(F)cc(F)cc1Br)c1cc(-c2ccc(O)cc2)on1
[b] C/C(=N\NC(=O)c1[nH]c2c([N+](=O)[O-])cc(C)cc2c1-c1ccccc1)c1cccnc1
[c] N#CC(C#N)=C(N)/C(C#N)=C/c1cc(O)c(O)c(O)c1
[d] COc1cccc(Cn2c(-c3cccs3)noc2=O)c1
Answer: d. COc1cccc(Cn2c(-c3cccs3)noc2=O)c1
