Bromobenzene in the presence of nitronium ions preferentially forms para-bromonitrobenzene rather than the meta or the ortho product. This means the reaction is .

Electrophilic aromatic substitution is the reaction in which the bromobenzene is present with the presence of the nitronium ions and results in the formation of para-bromonitrobenzene.

Explanation:

Bromobenzene in the presence of nitronium ions preferntially forms para-bromonitrobenzene rather than meta or the ortho product.

so. here the reaction been mentioned refers to Electrophilic  aromatic substitution.

Electrophilic  aromatic substitution: An organic reaction is referred as the aromatic substitution.

In this type of organic reaction a system is present which is an organic system to which an atom gets attached which get replaced by an electrophile.

It is one of the most important reactions of the field synthetic organic chemistry.

the usage of these reactions are in synthesis of the most important intermediates which are used as the precursors in agrochemical, industrial and pharmaceutical products.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
