Problem statement: Answer the multiple choice question.
Question: Which drug has a 5.127\% 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(Cc1ccccc1[N+](=O)[O-])OCc1cccc([N+](=O)[O-])c1
b: C#CC(CC)(CC)NC(=O)c1nn(-c2ccccc2Cl)c(C)cc1=O
c: COc1cc(C(=O)NNC(=S)NC(=O)c2ccc3c(c2)OCO3)cc(OC)c1OC
d: O=C(CSc1nnc(C2COc3ccccc3O2)o1)N1CCCCC1
Answer: a. O=C(Cc1ccccc1[N+](=O)[O-])OCc1cccc([N+](=O)[O-])c1
