Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.578\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCCCn1c(N)c(N(CCC(C)C)C(=O)c2sc3nc4n(c(=O)c3c2C)CCC4)c(=O)[nH]c1=O
b: CC(C)CC(CC(C)C)=NNC(=O)c1ccc2c(c1)OCO2
c: Cl.O=S(=O)(c1ccc2nc(Cc3ccccc3)[nH]c2c1)N1CCOCC1
d: Cc1ccc(C(=O)C(C)OC(=O)c2ccccc2[N+](=O)[O-])cc1
e: CC(=O)NCCNC(=O)c1ccc(Cn2c(=O)[nH]c3ccsc3c2=O)cc1
Answer: b. CC(C)CC(CC(C)C)=NNC(=O)c1ccc2c(c1)OCO2
