Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 1.525\% 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(CNC(=O)c1ccc(Br)cc1)NCCc1nc2ccccc2[nH]1
b O=C(c1cccc(OCc2ccccc2)c1)N1CCOCC1
Answer: a. O=C(CNC(=O)c1ccc(Br)cc1)NCCc1nc2ccccc2[nH]1
