Task: Answer the multiple choice question.
Question: Which compound has a 8.373\% 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(NCCc1ccccc1)C(=O)NCC1OCCN1S(=O)(=O)c1ccc(Br)cc1
b O=C(CCOc1ccccc1)Nc1cccc([N+](=O)[O-])c1
c COc1ccc(C(=O)c2c(-c3ccsc3)oc3ccc(-c4ccc(OC)cc4)cc23)cc1
d O=C(O)c1cc(-n2[nH]c(=O)c3ccccc3c2=O)ccc1Cl
e CCc1cccc(NC(=O)CCS(=O)(=O)c2cc3c(cc2C)NC(=O)CO3)c1
Answer: d. O=C(O)c1cc(-n2[nH]c(=O)c3ccccc3c2=O)ccc1Cl
