Task: Answer the multiple choice question.
Question: Which drug has a 26.182% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(NC(=S)NNC(=O)c1ccccc1O)c1cccc([N+](=O)[O-])c1
b Cc1ccc(C2c3c(oc4ccccc4c3=O)C(=O)N2c2nnc(C(C)C)s2)o1
c CCOC(=O)c1ccc(N2C(=O)Cc3ccccc3C2=O)cc1
d CC(=C/C(=O)O)/C=C/c1ccc(Cl)o1
Answer: a. O=C(NC(=S)NNC(=O)c1ccccc1O)c1cccc([N+](=O)[O-])c1
