Task: Answer the multiple choice question.
Query: Which drug exhibits a -10.507\% 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 additional words.
Options:
a) Cn1c(=O)n(CCOc2ccccc2Cl)c2ccccc21
b) Cc1c(NC(=S)Nc2cccc(Cl)c2)c(=O)n(-c2ccccc2)n1C
c) COCCCNC(=O)c1ccc2nc3ccccc3c(=O)n2c1
Answer: a. Cn1c(=O)n(CCOc2ccccc2Cl)c2ccccc21
