Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.293\% human ether-à-go-go related gene (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(Nc1ccc(Cl)cc1)N1CCC(CO)(Cc2ccccc2)CC1
b: Cl.NC(=NCc1ccccc1)c1cccc([N+](=O)[O-])c1
c: CCc1cn(S(=O)(=O)c2ccccc2OC)nc1N
d: CC(=O)N1CCC2(CC1)C(C#N)=C(N)Oc1c2sc2nc(C)cc(C)c12
Answer: a. O=C(Nc1ccc(Cl)cc1)N1CCC(CO)(Cc2ccccc2)CC1
