Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.927% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: Cc1sc(-n2c(C)ccc2C)c(C(=O)NN)c1C
b: CS(=O)(=O)c1ccc(C(=O)Nc2ccc(S(=O)(=O)N3CCCCC3)cc2)cc1
Answer: a. Cc1sc(-n2c(C)ccc2C)c(C(=O)NN)c1C
