Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.727\% 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 other words.
Options:
[a] O=C(O)c1ccc[n+](Cc2ccc([N+](=O)[O-])cc2)c1.[Br-]
[b] CCOC(=O)C1(CC/C(C)=N\NC(N)=O)CC(C)OC1=O
[c] N#CC1=C(N)Oc2cc(N)ccc2C1c1cc(Br)cs1
[d] Cc1ccc2cc([N+](=O)[O-])ccc2n1
Answer: a. O=C(O)c1ccc[n+](Cc2ccc([N+](=O)[O-])cc2)c1.[Br-]
