Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.065\% 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] O=C(Cc1ccccc1)NC1c2ccccc2-c2ccccc21
[b] COc1cc(OC)cc(C(=O)NCc2ccc3[nH]c(C)cc3c2)c1
Answer: a. O=C(Cc1ccccc1)NC1c2ccccc2-c2ccccc21
