Newton's third law states that every action has an equal and opposite reaction. The action and reaction forces are pairs of opposing forces.
In the given examples all three obey Newton's third law.
B) Action force: John pulls the door handle
Reaction: door handle gets pulled
C) Action force: Tire pushes on road
Reaction: The road pushes on the tire, vehicle moves
D) Action force: Exhaust pushes out of a rocket
Reaction: Rocket is pushed forward
Ans A) All these are examples of Newtons third law

Darwin's Theory of Evolution by Natural Selection.
Darwin divided this theory into multiple parts but overall it fits into Darwin's Theory of Evolution by Natural Selection, so that would be your answer.
In case you're wondering about the others:
1. Organisms produce more offspring than actually survive.
2. Every organism must struggle to survive.
3. There is variation within a species.
4. Some variations allow members of a species to survive and reproduce better than others.
5. Organisms that survive and reproduce pass their traits to their offspring, and the helpful traits gradually appear in more and more of the population.
(these are brief explanations, they go into more detail)
Good luck!
Answer:
3) Ionic
Explanation:
The solid formed when a bond occurs between magnesium and oxygen is an ionic bond. This bond type occurs between a metal and non-metal.
- Magnesium is the metal
- Oxygen is the non - metal
- Due to the large electronegativity difference between the two species, the metal loses electrons which the non-metal oxygen gains
- They both complete their octet and electrostatic attraction leads to the formation of ionic bonds.
