Task: Answer the multiple-choice question.
Question: Which drug exhibits a 24.818% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCCCOc1ccc(CON(C(C)=O)C(C)=O)cc1Cl
b: COc1ccccc1NC(C#N)c1ccccc1OCc1ccccc1
c: CCN1CCSc2ccc(C(=O)NCc3cccc(F)c3)cc21
d: COc1ccc(S(=O)(=O)N(C(=O)c2ccncc2)c2ccc(OC(=O)c3ccncc3)cc2)cc1
e: COc1ccc2c(c1)CCCN2S(=O)(=O)c1ccc(Cl)cc1
Answer: b. COc1ccccc1NC(C#N)c1ccccc1OCc1ccccc1
