Your friend pushes you for making fun of him/her. What is the reaction force?

In anticipation of the push from your friend, you had probably set a foot back where it could push on the ground and be pushed back in a way that balances the push from your friend. You may also have given your body some velocity toward your friend, so that your friends push would cancel its momentum.

If your friend had dodged your attempt to push instead of pushing back by starting to fall, you might have either stumbled in the direction of your intended push, or had to shift your weight to your forward foot in order to let the ground push you back instead.

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.
