Cloves are obtained from the aromatic flower buds of a tree in the family Myrtaceae, Syzygium aromaticum. Cloves ate the dried unopened flower buds and calyx tubes, harvested before the flowers have opened, of the clove tree. Cloves are collected when the flower bud is not yet open.

Correct Option: D

Nitrous oxide (N₂O) is a colorless, odorless gas that is used as an anesthetic and analgesic. It is used in surgery and dentistry for its anaesthetic and analgesic effects. It is known as “laughing gas” due to the euphoric effects of inhaling it, a property that has led to its recreational use as a dissociative anaesthetic.

In the process of photosynthesis, oxygen is produced from the photolysis of water. The photolysis of water occurs when light is used to renew split water and adenosine triphosphate, also referred to as ATP. The hydrogen remains in the leaf and participates in further reactions. 2H₂O(l) = Hydrogen + O₂(g)
