Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 3.667\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) O=C(CC[NH+]1CCCCC1)c1ccccc1.[Cl-]
b.) Cc1ccccc1C(=O)Nc1nnc(-c2ccco2)o1
c.) O=C(COc1ccccc1[N+](=O)[O-])N(Cc1ccccc1)c1ccccn1
d.) CCO[C@H]1OC(C(=O)Nc2ccccc2)=C[C@@H](c2cn(C(C)=O)c3ccccc23)[C@@H]1CCCO
Answer: d. CCO[C@H]1OC(C(=O)Nc2ccccc2)=C[C@@H](c2cn(C(C)=O)c3ccccc23)[C@@H]1CCCO
