Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 16.928\% 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: CCS(=O)(=O)Nc1cccc(-c2nc3cccnc3s2)c1
b: Cc1ccc(Nc2nc(C)cc(C)c2C(N)=O)cc1
c: CC1=C(C(=O)OC(C)C)[C@]2(C(=O)N(CC(N)=O)c3ccccc32)C(C#N)=C(N)O1
d: CCCN=C(C)C1=C(O)c2ccccc2C1=O
Answer: d. CCCN=C(C)C1=C(O)c2ccccc2C1=O
