Problem statement: Answer the multiple-choice question.
Query: Which drug has a 0.690\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCOc1cc(C(=O)O)cc(Cl)c1OC
[b] O=C(CNC(=O)C1CCCCC1)NNC(=O)c1ccc(Cl)cc1Cl
[c] Cc1nn(-c2ccccc2)c2c1C(c1ccccc1)C(C#N)=C(N)O2
[d] CC(=O)c1ccc2cccc3c2c1N=CN3C
Answer: c. Cc1nn(-c2ccccc2)c2c1C(c1ccccc1)C(C#N)=C(N)O2
