Problem statement: Answer the multiple choice question.
Question: Which drug has a 6.165\% 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] O=c1c2c(nc3cc(-c4ccc(Br)cc4)[nH]n13)CCCC2
[b] CCN(CC)C(=O)CCSc1nnc(-c2ccco2)o1
[c] COc1ccccc1/C=C1/C(=O)N(c2ccc([N+](=O)[O-])cc2)N=C1C
Answer: a. O=c1c2c(nc3cc(-c4ccc(Br)cc4)[nH]n13)CCCC2
