Task: Answer the multiple choice question.
Query: Which drug has a 23.261\% 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. CCN1CCN(c2nc(N(C)c3ccccc3)nc(N)c2[N+](=O)[O-])CC1
b. Cc1csc(=O)n1CC(=O)OCC(=O)N(CC(C)C)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
c. COc1cc(/C=C(/C#N)C(=O)c2c(C)[nH]c3ccccc23)ccc1OCC#N
d. O=C(O)CCc1c(C(=O)O)[nH]c2ccccc12
Answer: a. CCN1CCN(c2nc(N(C)c3ccccc3)nc(N)c2[N+](=O)[O-])CC1
