Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.135\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CCOC(=O)C1CCCN(C(=O)CCn2nnnc2CN2CCOCC2)C1
b: S=c1[nH]nc(Cc2ccccc2)n1-c1cccc2ccccc12
c: O=C(NNC(=O)C1C2CCCCC21)c1coc(=O)c(Br)c1
Answer: b. S=c1[nH]nc(Cc2ccccc2)n1-c1cccc2ccccc12
