Problem statement: Answer the multiple choice question.
Question: Which drug has a -24.668\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=[N+]([O-])c1ccc(O)c(C=Nc2ccc3oc(Cc4ccc(Cl)cc4)nc3c2)c1
b. CC1CN(C(=O)/C=C/c2ccc([N+](=O)[O-])s2)CC(C)O1
c. CC(NCC1(N2CCOCC2)CCCCC1)C(=O)Nc1ccc(Cl)cc1Cl.O=C(O)C(=O)O
d. O=C(c1cccc(-c2ccc(O)cc2)c1)N1CCOCC1
Answer: b. CC1CN(C(=O)/C=C/c2ccc([N+](=O)[O-])s2)CC(C)O1
