Task: Answer the multiple-choice question.
Query: Which drug exhibits a 21.605% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=C(Cc1ccccc1)O/N=C1\CCCc2ccccc21
b. O=C(NCc1ccccn1)C1CC(c2ccccc2O)=NO1
Answer: a. O=C(Cc1ccccc1)O/N=C1\CCCc2ccccc21
