Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 12.245\% 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) Cn1c(=S)c2[nH]c(SCCN3CCCC3)nc2n(C)c1=O
b) C=CCN(CC=C)S(=O)(=O)c1ncn[nH]1
Answer: a. Cn1c(=S)c2[nH]c(SCCN3CCCC3)nc2n(C)c1=O
