Task: Answer the multiple choice question.
Question: Which drug exhibits a 17.778\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:

b: Cc1ccc(CNC(=O)C2CCN(c3nc(C)cc(C)n3)CC2)cc1
c: CN(CC(=O)Nc1ccccc1Br)C(=O)c1cc([N+](=O)[O-])ccc1N1CCOCC1
d: CCC(C)NC(=O)CC(c1ccccc1)c1cc(C)ccc1O
Answer: c. CN(CC(=O)Nc1ccccc1Br)C(=O)c1cc([N+](=O)[O-])ccc1N1CCOCC1
