Task: Answer the MCQ question.
Query: Which compound exhibits a -47.660\% 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/C(=N\NC(=O)CNC(=O)C(c1ccccc1)c1ccccc1)c1ccc(C(C)(C)C)cc1
b: O=C(NCc1n[nH]c(=S)n1-c1ccc(Br)cc1)c1cccs1
c: Cc1nn(-c2ccccc2)c(N2CCCC2)c1/C=N/NC(=O)c1cc(-c2cccnc2)nc2ccccc12
d: CC(C)(C)N(Cc1ccccc1)C(=O)COC(=O)c1cccc([N+](=O)[O-])c1
e: COc1ccc(CN2CCN(c3ccccc3OC)CC2)c(OC)c1.O=C(O)C(=O)O
Answer: e. COc1ccc(CN2CCN(c3ccccc3OC)CC2)c(OC)c1.O=C(O)C(=O)O
