Problem statement: Answer the multiple choice question.
Query: Which drug has a 2.152% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCCCn1c(SCC(=O)c2cc(OC)ccc2OC)nc2cc(S(N)(=O)=O)ccc21
b: COc1ccc(N/C(=C/[N+](=O)[O-])SC)cc1
Answer: a. CCCCn1c(SCC(=O)c2cc(OC)ccc2OC)nc2cc(S(N)(=O)=O)ccc21
