Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.783% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. NC(=O)CC(NC(=O)c1ccccc1)c1ccc(NC2CCN(Cc3ccccc3)CC2)c([N+](=O)[O-])c1
b. CCc1ccccc1NC(=O)Nc1ccc(F)cc1F
c. CCc1cc(C(=O)O)c(NC(=O)C(c2ccccc2)c2ccccc2)s1
d. O=C(Nc1ccccc1)C1=C[C@H](c2csc3ccccc23)C[C@H](OCCCCO)O1
e. CC(=O)Nc1ccc(S(=O)(=O)N(C)CC(=O)OCC(=O)N2CCCCC2)cc1
Answer: b. CCc1ccccc1NC(=O)Nc1ccc(F)cc1F
