Task: Answer the MCQ question.
Question: Which compound exhibits a 7.555\% 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] CCOC(=O)N1CCC(NS(=O)(=O)c2ccc3c(c2)CCN3C(C)=O)CC1
[b] O=C1C(=O)N(CCCO)C(c2ccc(Br)cc2)/C1=C(\O)c1ccc(Br)cc1
Answer: b. O=C1C(=O)N(CCCO)C(c2ccc(Br)cc2)/C1=C(\O)c1ccc(Br)cc1
