Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.238\% 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, or c without using any other words.
Options:
a.) COc1ccc(NC(=O)CN(C)C(=O)/C=C/c2cn(-c3ccccc3)nc2-c2ccc(C)cc2)cc1
b.) CCOCCCNC(=O)Cn1cnc2c(cnn2-c2ccc(OC)cc2)c1=O
c.) Cn1c(CN2CCCC2)nc2cc(NC(=O)Nc3ccccc3)ccc21
Answer: b. CCOCCCNC(=O)Cn1cnc2c(cnn2-c2ccc(OC)cc2)c1=O
