Task: Answer the multiple choice question.
Query: Which compound exhibits a -1.565\% 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. C/C(=N\NC(=O)c1ccccc1O)c1ccc(NC(=O)c2ccccc2)cc1
b. O=C(c1ccc2c3n(nc2c1)-c1ccc(Cl)cc1CO3)N1CCCCC1
Answer: b. O=C(c1ccc2c3n(nc2c1)-c1ccc(Cl)cc1CO3)N1CCCCC1
