Task: Answer the multiple-choice question.
Query: Which drug has a 8.689\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] C/C(=N\N=C(N)N)c1ccccc1
[b] Cc1ccc(C(=S)N2CCN(Cc3ccccc3)CC2)cc1
[c] CCOC(=O)c1cnc(C(C)(C)C)[nH]c1=O
Answer: c. CCOC(=O)c1cnc(C(C)(C)C)[nH]c1=O
