Task: Answer the multiple choice question.
Question: Which drug has a 14.656% 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(c1cccc(Br)c1)c1coc2ccc(O)cc12
b: Cc1[nH]c2ccccc2c1CCN(Cc1cccs1)C(=S)NC(C)(C)C
Answer: a. O=C(c1cccc(Br)c1)c1coc2ccc(O)cc12
