Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.965\% 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 or b without using any additional words.
Options:
a) COc1ccccc1C(=O)NNC(=O)CCCN1C(=O)/C(=C/c2cccs2)SC1=S
b) CC(C)CN1CCN=C1N(C)C
Answer: b. CC(C)CN1CCN=C1N(C)C
