Problem statement: Answer the multiple choice question.
Question: Which drug has a 12.243\% 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 other words.
Options:
a COc1ccc(NC(=O)c2ccccc2SC)cc1
b O=c1ccc2c(-c3ccccc3)c3ccc(O)cc3oc-2c1
c COc1ccccc1N1CCN(C(c2ccccc2Cl)c2nnnn2C(C)(C)C)CC1.Cl
Answer: b. O=c1ccc2c(-c3ccccc3)c3ccc(O)cc3oc-2c1
