Task: Answer the multiple-choice question.
Question: Which compound exhibits a 11.775\% 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) O=C(CNC(=O)c1ccncc1)N/N=C/c1ccccn1
b) COCCn1c(SCC(=O)Nc2ccccc2OC)nnc1-c1ccco1
c) Cc1[nH]n(-c2nc(-c3ccc(Cl)cc3)cs2)c(=O)c1N=Nc1ccc(O)cc1
Answer: a. O=C(CNC(=O)c1ccncc1)N/N=C/c1ccccn1
