Task: Answer the multiple-choice question.
Question: Which compound has a 8.448\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) CCOC(=O)/C(C#N)=C/c1cc2ccccc2nc1N1CCCCC1
b.) Cn1ncc(Br)c1C(=O)N1CCCC1
c.) Cn1c(=O)c2c(nc(N3CCN(c4ccc([N+](=O)[O-])cc4)CC3)n2C)n(C)c1=O
d.) CCOC(=O)c1[nH]ncc1CN1CCC(Cc2cccc(OC)c2)(C(=O)OCC)CC1
e.) N#Cc1c(NCCN)nc(-c2ccccc2)c2c1CCCC2
Answer: a. CCOC(=O)/C(C#N)=C/c1cc2ccccc2nc1N1CCCCC1
