Task: Answer the multiple choice question.
Query: Which compound exhibits a -6.812\% 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. Cc1ccc(C)c(COC(=O)CCN=C2NS(=O)(=O)c3ccccc32)c1
b. O=c1c(-c2ccccc2)c(-c2ccccc2)oc2cc(O)cc(O)c12
c. O=c1c(CN2CCN(c3ccccn3)CC2)coc2ccccc12
Answer: c. O=c1c(CN2CCN(c3ccccn3)CC2)coc2ccccc12
