Which compound acts as a ligand for peroxisome proliferator-activated receptors (PPARs), a class of nuclear hormone receptors that regulate genes involved in the metabolism of glucose and lipids?

Explanation

Rosiglitazone binds to PPAR receptors, a group of nuclear hormone receptors that control the expression of genes related to glucose and lipid metabolism. Other options like Repaglinide, Voglibose, and Exenatide do not target PPARs.
