Task: Answer the multiple choice question.
Query: Which drug has a 6.554\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) Cc1ccc(N=Cc2sccc2C)cc1C
b.) C/C(=N\NC(=O)c1ccccc1)c1c(C)[nH]n(-c2ccccc2)c1=O
c.) O=C(NCc1cccnc1)Nc1ccc(Br)cc1
Answer: c. O=C(NCc1cccnc1)Nc1ccc(Br)cc1
