Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -30.591% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CCn1nc(C)c(/C=C2\CCCC3=C2OC(N)=C(C#N)C3c2c(C)nn(CC)c2C)c1C
[b] C[n+]1c(-c2ccccc2)cc(CCCCc2cc(-c3ccccc3)[n+](C)c(-c3ccccc3)c2)cc1-c1ccccc1.[O-][Cl+3]([O-])([O-])[O-]
[c] CCC1(C(=O)c2ccccc2)C(c2cccc([N+](=O)[O-])c2)C1(C(=O)OC)C(=O)OC
Answer: b. C[n+]1c(-c2ccccc2)cc(CCCCc2cc(-c3ccccc3)[n+](C)c(-c3ccccc3)c2)cc1-c1ccccc1.[O-][Cl+3]([O-])([O-])[O-]
