Task: Answer the multiple-choice question.
Question: Which compound exhibits a 4.841\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a O=C(Nc1nc2ccc([N+](=O)[O-])cc2s1)C1CCCO1
b O=S(=O)(CC(O)COc1ccc(Br)cc1)c1ccccc1
c CCc1nnc(N/N=C/c2ccccc2F)n1N.Cl
d COCCNC(=O)Cn1cc(/C=N/NC(=O)c2ccc(Oc3ccc(O)cc3)cc2)c2ccccc21
e CCc1ccc(CNC(=O)CCc2cn(C)c3ccccc23)cc1
Answer: a. O=C(Nc1nc2ccc([N+](=O)[O-])cc2s1)C1CCCO1
