Problem statement: Answer the multiple choice question.
Question: Which drug has a 21.115\% 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=C(Nc1cc(=O)[nH]c(=O)[nH]1)c1cccc(Br)c1
b.) COc1ccccc1Nc1ccc([N+](=O)[O-])cn1
c.) COc1ccccc1NC(=S)NC(=O)CCCOc1ccc(Cl)cc1Cl
d.) Cc1cc(C(=O)OCCO)c(C#N)c(N)n1
Answer: d. Cc1cc(C(=O)OCCO)c(C#N)c(N)n1
