Task: Answer the MCQ question.
Query: Which compound exhibits a 15.069\% 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(CCCN1C(=O)/C(=C\c2cccs2)SC1=S)Nc1cc([N+](=O)[O-])ccc1O
[b] Cc1ccc(CCNC(=O)C2CCN(S(=O)(=O)N3CCCC3)CC2)cc1
Answer: a. O=C(CCCN1C(=O)/C(=C\c2cccs2)SC1=S)Nc1cc([N+](=O)[O-])ccc1O
