Task: Answer the MCQ question.
Query: Which compound has a 21.144% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C1CC(C(=O)Nc2cccc(F)c2)n2c(nc3ccccc32)N1
b CCC(C)(C)NC(=O)C(c1cccn1C)N(C(=O)Cn1nnc2ccccc21)c1ccc(NC(C)=O)cc1
c N/N=C(\Cc1cscn1)c1ccc(O)cc1O
Answer: a. O=C1CC(C(=O)Nc2cccc(F)c2)n2c(nc3ccccc32)N1
