Task: Answer the multiple-choice question.
Query: Which drug exhibits a 0.596\% 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 other words.
Options:
a.) O=C(Nc1cccc2nsnc12)c1ccc(F)cc1
b.) NC(=O)COC(=O)c1cccc(S(=O)(=O)N2CCN(c3ccc(F)cc3)CC2)c1
c.) CCCCOC(=O)Nc1ccc(N2CCCCC2)cc1
d.) COCCC(=O)NC12CC3CC(CC(C3)C1)C2
Answer: a. O=C(Nc1cccc2nsnc12)c1ccc(F)cc1
