Problem statement: Answer the multiple choice question.
Question: Which drug has a 3.509\% 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 additional words.
Options:
a. OCc1ccc(N=Nc2ccccc2)cc1
b. S=C1NCN(C2CCCCC2)CN1Cc1ccccc1
c. O=C(CCc1nc2ccccc2c(=O)[nH]1)NNC(=O)COc1ccc(Br)cc1
Answer: c. O=C(CCc1nc2ccccc2c(=O)[nH]1)NNC(=O)COc1ccc(Br)cc1
