Explanation:

Electrophilic aromatic substitution reaction refers to the replacement of a hydrogen atom on an arene ring by an electrophile. This reaction is difficult with unsubstituted benzene. However, substituents such as alkoxy and alkyl groups increases the tendency of the ring to participate in electrophilic substitution reactions due to electron donation to the ring. Other substituents, decrease the tendency of the ring to participate in electrophilic substitution and are said to deactivate the ring.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
