Task: Answer the multiple choice question.
Question: Which drug exhibits a 10.350\% 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] Cl.OCCN1C2=NCCCN2c2ccccc21
[b] C[C@@H]1CC=C[C@H]2[C@H]1C(=O)N(Cc1ccccc1)[C@H]2c1ccc(-c2ccc(F)cc2)cc1F
Answer: a. Cl.OCCN1C2=NCCCN2c2ccccc21
