Task: Answer the multiple choice question.
Query: Which compound has a 13.936% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) NC(=O)C1CCN(/C=C2\C(=O)NC(=O)N(Cc3ccco3)C2=O)CC1
b) CCc1ccccc1NC(=O)c1cc(=O)c2ccccc2o1
c) Cn1ccnc1C1CCCCN1Cc1nc(-c2ccc(Cl)cc2)no1
d) O=C1NC(c2ccccc2)Oc2ccccc21
Answer: d. O=C1NC(c2ccccc2)Oc2ccccc21
