Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.883\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. Cc1c(Cl)c([N+](=O)[O-])nn1CC(=O)N1CCCC1
b. COc1cccc(/C=N\NC(=O)c2ccc(Cn3cc(Br)c([N+](=O)[O-])n3)o2)c1O
c. CCOC(=O)C(C)n1nc(/C=C/c2ccccc2)ccc1=O
d. C#CCNC(=O)C1=C[C@H](c2cn(C(C)=O)c3ccccc23)C[C@H](OCc2ccc(CO)cc2)O1
e. COc1ccc(-c2csc(NC(=O)c3ccc(OCC(=O)N4CCOCC4)c(OC)c3)n2)cc1OC
Answer: a. Cc1c(Cl)c([N+](=O)[O-])nn1CC(=O)N1CCCC1
