Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.289\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCOc1cc2c3c(c1)C1(Nc4ccccc4S1)C(=O)N3C(C)(C)CC2C
b: Cc1c(C(c2cccc([N+](=O)[O-])c2O)c2c(C)n(C)n(-c3ccccc3)c2=O)c(=O)n(-c2ccccc2)n1C
c: CC(C)(C)OC(=O)[C@H](Cc1ccccc1)NC(=O)c1nc[nH]c1C(=O)N[C@@H](Cc1ccccc1)C(=O)OC(C)(C)C
d: Cc1nc2sc(-c3ccccc3)cc2c(=O)[nH]1
Answer: b. Cc1c(C(c2cccc([N+](=O)[O-])c2O)c2c(C)n(C)n(-c3ccccc3)c2=O)c(=O)n(-c2ccccc2)n1C
