Task: Answer the multiple choice question.
Query: Which drug has a 9.491\% human ether-à-go-go related gene (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) CCOC(=O)C1CCN(c2nc3cc(OC)ccc3cc2C#N)CC1
b) O=C(OCC(=O)c1ccc[nH]1)C1=COCCO1
c) NC(=O)c1ccc[n+](CC(=O)c2cccc([N+](=O)[O-])c2)c1.[Br-]
d) Cc1cccc(C)c1NC1=NCCCCS1
Answer: b. O=C(OCC(=O)c1ccc[nH]1)C1=COCCO1
