Task: Answer the multiple choice question.
Query: Which compound exhibits a 14.127\% 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 CCCCN(CCO)CCCC
b COc1ccc(C(=O)NNC(=O)c2ccccn2)cc1
c Cc1cc(C)nc(-n2ncc3c2CC(c2ccccc2C)CC3=O)n1
d Cc1cccc(NC(=O)CN(CCc2ccccc2)S(C)(=O)=O)c1
Answer: b. COc1ccc(C(=O)NNC(=O)c2ccccn2)cc1
