Which of the following elements is known to influence the body's ability to handle oxidative stress?

Ans. is 'd' i.e., Selenium* Selenium would be the mineral most specifically related to antioxidant function.* There are at least 35 antioxidant Se proteins and include selenoprotein P, five glutathione peroxidases and three thioredoxin reductases (TrXRl). Most recent research indicates TrXRl reduces harmful ROS and facilitates gene expression of other cytoprotective antioxidants* Selenium as part of glutathione peroxidase (GSH-Px) is the 2nd line of defense as the enzyme destroys peroxides and hydroperoxides.* Apart from selenium, Mn, Cu, Zn, Fe help to maintain the efficient levels of endogenous antioxidants in the tissues.
