Problem statement: Answer the MCQ question.
Query: Which drug has a 10.913% 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 other words.
Options:
a: COCCNCCCCOc1ccc(C)cc1[N+](=O)[O-].O=C(O)C(=O)O
b: CCc1ccccc1NCC(=O)Nc1ccc(Cl)c(C(F)(F)F)c1
c: O=c1[nH]c2ccccc2c(O)c1O
d: COc1cccc(C(=O)Nc2ccccc2-c2ccccc2)c1
Answer: c. O=c1[nH]c2ccccc2c(O)c1O
