Task: Answer the multiple choice question.
Question: Which drug exhibits a 10.800\% 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, or d without using any other words.
Options:
a. N=C1C=CC=C2C1=NC1(CCCCC1)N2O
b. COc1ccc(-c2cc3c(nn2)-c2ccccc2C3=O)cc1
c. CCCOc1ccc(C(=O)Nc2ccc3c(c2)OCO3)cc1
d. COc1cccc(-c2nnc(-c3ccccc3[N+](=O)[O-])o2)c1
Answer: d. COc1cccc(-c2nnc(-c3ccccc3[N+](=O)[O-])o2)c1
