Task: Answer the multiple choice question.
Query: Which drug exhibits a 17.581\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) O=C1/C(=C\c2ccco2)NC(=S)N1c1ccccc1
(b) Cc1cccc(OCCCC(=O)Nc2ccc(S(=O)(=O)Nc3ncccn3)cc2)c1C
Answer: a. O=C1/C(=C\c2ccco2)NC(=S)N1c1ccccc1
