Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.509\% 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, c, or d without using any additional words.
Options:
a) Cc1oc(-c2cccc(Cl)c2)nc1CS(=O)(=O)CC(=O)NCCN1CCCC1
b) COc1ccc(-c2cc(C(=O)NCCCn3ccnc3)c3ccccc3n2)c(OC)c1
c) O=[N+]([O-])c1cc(CS(=O)(=O)Oc2ccc(Cl)cc2)c(O)c([N+](=O)[O-])c1
