Task: Answer the multiple choice question.
Question: Which compound exhibits a -0.947\% 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(NCCc1ccc(Cl)cc1)c1ccc2c(c1)OCO2
(b) CS(=O)(=O)O.c1ccc(-c2ccc3c(c2)c2c4n3CCN=C4CCC2)cc1
(c) COc1cc2cc(C)nc(Cc3cccc4ccccc34)c2cc1OC
Answer: a. O=C(NCCc1ccc(Cl)cc1)c1ccc2c(c1)OCO2
