Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.555\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] Cc1cc(C2=NNC(=Nc3ccc(S(=O)(=O)N4CCOCC4)cc3)SC2)c(C)n1C
[b] COc1ccccc1/C=C/c1nc(S(=O)(=O)c2ccccc2)c(N2CCC(C(N)=O)CC2)o1
Answer: a. Cc1cc(C2=NNC(=Nc3ccc(S(=O)(=O)N4CCOCC4)cc3)SC2)c(C)n1C
