Problem statement: Answer the multiple choice question.
Question: Which drug has a 11.904\% 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 other words.
Options:
a: CCOc1ccccc1N1CCN(C(=O)CN2C(=O)NC3(CCCC3)C2=O)CC1
b: O=C1C(=O)N(CNc2cccnc2)c2ccccc21
c: Cn1c(N)c(C(=O)CSc2nc(N)cc(=O)[nH]2)c(=O)n(C)c1=O
d: COC(=O)C1=C(C)N(C)C(=O)NC1c1ccc([N+](=O)[O-])o1
Answer: b. O=C1C(=O)N(CNc2cccnc2)c2ccccc21
