Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.040\% 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 CC(=O)c1cccc(NC(=O)CN2C(=O)NC3(CCCCCCC3)C2=O)c1
b O=C(NC1CCCc2ccccc21)c1ccccc1Cl
c CCOC(=O)CSc1nc2sccc2c(=O)[nH]1
Answer: c. CCOC(=O)CSc1nc2sccc2c(=O)[nH]1
