Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 8.608\% 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, d, or e without using any additional words.
Options:
a.) CCNC(=O)Nn1c(-c2ccccc2)nc2ccccc2c1=O
b.) CCCn1nc([N+](=O)[O-])c(C(C#N)c2nc3ccccc3o2)c(Cl)c1=O
c.) COc1ccc(S(=O)(=O)n2nc(OC(=O)C3CCCCC3)cc2N)cc1
d.) Cc1cccc(CNC(=O)CCn2ccc3cc(S(=O)(=O)N4CCCC4)ccc32)c1
e.) CCOC(=O)C1CCN(C(=O)/C=C/c2ccccc2)CC1
Answer: b. CCCn1nc([N+](=O)[O-])c(C(C#N)c2nc3ccccc3o2)c(Cl)c1=O
