Task: Answer the multiple choice question.
Question: Which compound has a 18.990\% 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 other words.
Options:
a) CCC1(c2ccccc2)NC(=O)N(CC(=O)NCc2ccc(OC)cc2)C1=O
b) O=C1NN(c2ccccc2)C(=O)/C1=C/c1ccc(-c2ccc(C(=O)O)cc2)o1
c) O=C(/C=C/c1ccccc1[N+](=O)[O-])NCc1ccccc1Cl
d) Cc1nc2cc(C(=O)OCC(=O)Nc3ccc(C#N)cc3)ccc2n1-c1ccccc1
e) CSc1cccc(NC(=O)C2CCCN(c3ncnc4c3nc3n4CCCCC3)C2)c1
Answer: b. O=C1NN(c2ccccc2)C(=O)/C1=C/c1ccc(-c2ccc(C(=O)O)cc2)o1
