Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 18.057\% 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, or c without using any additional words.
Options:
[a] O=C(CN1C(=O)CCOc2ccccc21)Nc1cccc(S(=O)(=O)N2CCOCC2)c1
[b] O=C(c1cccs1)c1cn(Cc2ccccc2Cl)c2ccccc12
[c] CCc1ccc(/C=N/NC(=O)Cc2cccn2C)cc1
Answer: b. O=C(c1cccs1)c1cn(Cc2ccccc2Cl)c2ccccc12
