Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.275% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=c1[nH]c(Cn2nnc(-c3ccccc3)n2)nc2scc(-c3ccccc3)c12
b CCCCN(CCCC)S(=O)(=O)c1ccc(NC(=O)c2cccs2)cc1
Answer: a. O=c1[nH]c(Cn2nnc(-c3ccccc3)n2)nc2scc(-c3ccccc3)c12
