Task: Answer the MCQ question.
Query: Which drug exhibits a 12.486\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a CCC(C)NC(=O)C(NS(=O)(=O)c1cccc2nsnc12)c1ccccc1
b C=CC[C@]12CC=CC(=O)[C@@]1(O)O[C@H](c1ccc(OC)c(OC)c1)[C@H]2C
c Cn1c(=O)c(C=Nc2ccccc2)c(O)c2ccccc21
Answer: c. Cn1c(=O)c(C=Nc2ccccc2)c(O)c2ccccc21
