Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.150\% 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.) CCOc1ccc(Br)cc1C(=O)N/N=C/c1c[nH]c2ccccc12
b.) COC(=O)C1=C(NC(=O)c2ccccc2[N+](=O)[O-])CCS1
c.) COc1ccc(C(O)c2nccn2C)cc1
d.) CCOC(=O)C(C(=O)OCC)C(C)(C)/C(C)=N\Nc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
Answer: b. COC(=O)C1=C(NC(=O)c2ccccc2[N+](=O)[O-])CCS1
