Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.295\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: C=C1CCN(C(C)C(=O)OC)S(=O)(=O)c2ccccc21
b: Cc1nnc2ccc(N3CCOCC3)nn12
c: COc1cc(OC)cc(-c2cc3ccc(OC)cc3cn2)c1
d: CN1CC2([N+](=O)[O-])CC=C(OCCO)C([N+](=O)[O-])(C1)C2
e: O=[N+]([O-])c1ccc(C2CCCC/C2=N/O)c([N+](=O)[O-])c1
Answer: c. COc1cc(OC)cc(-c2cc3ccc(OC)cc3cn2)c1
