Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.611\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COC(=O)c1cc2c(cc1Cl)SC(=NCCCN1CCOCC1)NS2(=O)=O
[b] NNC(=O)[C@@H]1C[C@@H]1c1ccccc1
[c] Cc1cc([N+](=O)[O-])ccc1NCc1ccccc1
[d] Cn1cc([N+](=O)[O-])c(C(=O)Nc2ccn(C34CC5CC(CC(C5)C3)C4)n2)n1
Answer: a. COC(=O)c1cc2c(cc1Cl)SC(=NCCCN1CCOCC1)NS2(=O)=O
