Problem statement: Answer the multiple choice question.
Question: Which drug has a -15.346% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(Nc1ccccc1-c1ccccc1)c1cnccn1
[b] Oc1c(Br)cc(Br)cc1Br
[c] CC(=O)c1c(Cl)nc2cccc3c2c1-c1ccccc1C3=O
[d] COc1ccc(N/C(C)=C2/C(=O)C(=O)N(CCO)C2c2ccc([N+](=O)[O-])cc2)cc1
Answer: a. O=C(Nc1ccccc1-c1ccccc1)c1cnccn1
