Task: Answer the multiple choice question.
Query: Which compound has a -1.425\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) CCCc1ccc(OCc2nc(-c3ccc(NC(=O)c4ccco4)cc3)no2)cc1
b.) O=C(CN(CC1CCCO1)S(=O)(=O)c1ccc(S(=O)(=O)NCC2CCCO2)cc1)Nc1ccccc1
c.) COC(=O)c1cc(-c2c(C)oc3cc(O)ccc3c2=O)c(C)o1
Answer: c. COC(=O)c1cc(-c2c(C)oc3cc(O)ccc3c2=O)c(C)o1
