Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.018\% 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 O=C(NN=C1CCCCC1)Nc1ccccc1Cl
b CCC(C)[C@H](NC(=O)NC1CCCc2ccccc21)C(=O)OC
c CCn1c(SCC(=O)Nc2ccccc2OC)nc(O)cc1=O
d COc1ccc(-c2csc(-c3ccccc3)n2)c(OC)c1
Answer: b. CCC(C)[C@H](NC(=O)NC1CCCc2ccccc21)C(=O)OC
