Task: Answer the multiple choice question.
Query: Which drug has a 4.887\% hERG inhibition at a concentration of 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(c1ccccc1)c1nn(-c2cccc(Cl)c2)ccc1=O
b. CC(NC(=O)c1ccco1)c1nc(-c2ccccc2Cl)no1
c. Nc1ccc(-c2nc3ncccc3o2)c(O)c1
d. O=C(CN(Cc1ccc(F)cc1)C(=O)CNS(=O)(=O)c1ccc(F)cc1)NCc1ccco1
Answer: c. Nc1ccc(-c2nc3ncccc3o2)c(O)c1
