Task: Answer the multiple choice question.
Question: Which drug has a 17.738\% human ether-à-go-go related gene (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. CCc1cccc(OCC(=O)N(C)CC(=O)Nc2cccc(F)c2)c1
b. O=c1c2c(nc3nc(NCc4ccccc4Cl)[nH]n13)CCC2
c. O=C1Nc2cc(Br)ccc2C1(O)c1ccccc1O
Answer: c. O=C1Nc2cc(Br)ccc2C1(O)c1ccccc1O
