Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.541\% human ether-à-go-go related gene (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 COc1ccc(N/C(=C(/C(Cl)=C(Cl)Cl)[N+](=O)[O-])n2nnc3ccccc32)cc1OC
b Cc1nnc(NS(=O)(=O)c2ccc(N)cc2)s1
c O=C(CCCC(=O)OCC(=O)c1cccs1)Nc1ccc(F)cc1
Answer: a. COc1ccc(N/C(=C(/C(Cl)=C(Cl)Cl)[N+](=O)[O-])n2nnc3ccccc32)cc1OC
