Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 9.854% 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] CC1(C)CC(=O)C(C=NCCN2CCN(CCCCS(=O)(=O)O)CC2)=C(O)C1
[b] CCn1cnc2c([N+](=O)[O-])c(NS(=O)(=O)c3ccc(C)cc3)ccc21
Answer: a. CC1(C)CC(=O)C(C=NCCN2CCN(CCCCS(=O)(=O)O)CC2)=C(O)C1
