Task: Answer the multiple-choice question.
Query: Which compound has a 11.988% 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.) NC(=O)C1=C[C@H](c2ccc3c(c2)OCO3)C[C@H](OCc2ccc(CO)cc2)O1
b.) CCC(C)[C@H](NC(=O)NCCCN1CCOCC1)C(=O)OC
Answer: b. CCC(C)[C@H](NC(=O)NCCCN1CCOCC1)C(=O)OC
