Task: Answer the multiple-choice question.
Query: Which drug has a -5.000% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cl.OC(CC#CCN1CCOCC1)(c1ccccc1)c1ccccc1
b: O=C(NCCN1CCCC1=O)Nc1ccccc1
c: O=[N+]([O-])c1ccc(S(=O)(=O)N2CCN=C2SCc2ccc(F)cc2)cc1
Answer: b. O=C(NCCN1CCCC1=O)Nc1ccccc1
