Task: Answer the multiple choice question.
Query: Which drug has a 1.515\% 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 additional words.
Options:
a: C/C(=N\NC(=O)c1ccccc1)c1cccc(Br)c1
b: Cc1ccc(NC(=O)c2cncc(Br)c2)c([N+](=O)[O-])c1
c: CCc1ccc(CNC(=O)C2CC(=O)N(C3CCCC3)C2)cc1
d: CSc1ccccc1NC(=O)CN(Cc1ccc(Cl)cc1)S(C)(=O)=O
e: O=C(c1ccc2c(=O)n(-c3ccccc3)c(=S)[nH]c2c1)N1CCCCC1
Answer: b. Cc1ccc(NC(=O)c2cncc(Br)c2)c([N+](=O)[O-])c1
