Task: Answer the MCQ question.
Question: Which compound exhibits a 12.480% 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(CSc1nnc(-c2cccs2)n1-c1ccccc1)N1CCCc2ccccc21
[b] COc1ccccc1N(CC(=O)NC1CCCC1)C(=O)C1(C)CC(=O)N=C2C=CC(C)=CN21
Answer: b. COc1ccccc1N(CC(=O)NC1CCCC1)C(=O)C1(C)CC(=O)N=C2C=CC(C)=CN21
