Problem statement: Answer the multiple choice question.
Query: Which drug has a -3.436\% human ether-à-go-go related gene (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) Cc1cc[n+](Cc2ccc([N+](=O)[O-])cc2)cc1.[Br-]
b) CCOc1cc(C(=O)OCC(=O)c2c[nH]c3ccccc23)ccc1OCC(=O)N1CCOCC1
c) Br.C=CCn1c(=N)n(CC(=O)c2ccc(Br)s2)c2ccccc21
Answer: c. Br.C=CCn1c(=N)n(CC(=O)c2ccc(Br)s2)c2ccccc21
