Task: Answer the multiple choice question.
Query: Which compound exhibits a 5.244\% 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 other words.
Options:
a. O=C(NC(c1ccccc1)c1ccccc1)N1CCN(CCO)CC1
b. Cc1ccc(OCc2nc3ccccc3nc2C)cc1
Answer: a. O=C(NC(c1ccccc1)c1ccccc1)N1CCN(CCO)CC1
