Task: Answer the multiple choice question.
Query: Which compound has a -4.927% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) C=CCNc1nnc(Sc2ncccc2[N+](=O)[O-])s1
b) Cc1ccc(S(=O)(=O)N(C)C)cc1NC(=O)C(C)OC(=O)c1ccc2ccccc2n1
c) Cc1c(NC(=O)c2ccccc2)c(=O)n(-c2ccccc2)n1C
Answer: a. C=CCNc1nnc(Sc2ncccc2[N+](=O)[O-])s1
