Task: Answer the MCQ question.
Question: Which compound has a 3.203\% 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, d, or e without using any other words.
Options:
a: O=C(COc1ccccc1)NC1CCCCC1
b: CCOC(=O)CNC(=O)CN1CCCN(S(=O)(=O)c2ccc(Br)s2)CC1
c: CCCCN(C(=O)NC(=O)Nc1c(C)cc(C)cc1C)S(C)(=O)=O
d: CC1(C)CC(=O)C2=C(C1)OC(N)=C([N+](=O)[O-])C2c1ccc(C#N)s1
e: Cc1cc(C)nc(Nc2ccc(N3CCOCC3)cc2)n1
Answer: d. CC1(C)CC(=O)C2=C(C1)OC(N)=C([N+](=O)[O-])C2c1ccc(C#N)s1
