Problem statement: Answer the multiple choice question.
Query: Which drug has a 7.535\% 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] O=C(O)CCCN1C(=O)c2ccccc2Sc2ncccc21
[b] CCCCCOC(=O)C1=C(C)Nc2nnnn2C1c1ccccc1Cl
[c] O=C(CCCc1ccccc1)Nc1ccnn1C1CCN(Cc2ccccc2F)CC1
Answer: a. O=C(O)CCCN1C(=O)c2ccccc2Sc2ncccc21
