b. the stomata close, cutting off transpiration and gas exchange.
c. the roots begin to rot, causing them to no longer uptake water.
d. the plant begins absorbing oxygen and releasing carbon dioxide into the atmosphere.

The stomata close, cutting off transpiration and gas exchange. - B

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
