Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.742\% 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 additional words.
Options:
a) COc1ccc(C(=O)N(CCc2ccccc2)Cc2cccs2)c(OC)c1
b) CCN(CC)c1ccc(/C=C/[N+](=O)[O-])cc1
c) COc1ccc(-c2c(C)oc3c(CN4CCCCC4C)c(O)ccc3c2=O)cc1OC
d) CC(=O)c1c(C)cc(C)c(CSc2nnc(-c3ccco3)o2)c1C
Answer: b. CCN(CC)c1ccc(/C=C/[N+](=O)[O-])cc1
