Task: Answer the multiple choice question.
Question: Which compound exhibits a 16.303\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C(NCCc1c[nH]c2ccccc12)Nc1ccccc1
b CC(C)CC(=O)N1CCC(O)(CS(=O)(=O)Cc2ccccc2Cl)CC1
c CC(=O)c1cc(CN2CCC(C(=O)Nc3cccc(-c4cscn4)c3)CC2)cs1
Answer: a. O=C(NCCc1c[nH]c2ccccc12)Nc1ccccc1
