Task: Answer the multiple choice question.
Query: Which compound exhibits a 12.448\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1ccccc1-c1nnc(SC)n1C
b: COCCNC(=O)[C@H](CSCc1ccccc1)N1Cc2ccccc2C1=O
c: CC(=O)NC12CC3CC(C1)CC(C(=O)Nc1nccs1)(C3)C2
d: Cn1c(=O)c2c(SCC(=O)NC3CCCC3)nc(CC(C)(C)C)nc2n(C)c1=O
Answer: d. Cn1c(=O)c2c(SCC(=O)NC3CCCC3)nc(CC(C)(C)C)nc2n(C)c1=O
