Task: Answer the multiple choice question.
Question: Which compound exhibits a 9.938\% 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, b, c, or d without using any other words.
Options:
(a) CCc1ccc(NC(=O)CNC(=O)c2nn(-c3ccc(OC)cc3)c(=O)c3ccccc23)cc1
(b) CCOC(=O)COc1ccccc1/C=C1/NC(=O)NC1=O
(c) CC1(C)CC(=O)c2c(-c3cccs3)n[nH]c2C1
(d) CSc1nc2c(c(=O)[nH]c(=O)n2C)n1Cc1ccccc1Cl
Answer: b. CCOC(=O)COc1ccccc1/C=C1/NC(=O)NC1=O
