The correct answer is Principle of Inertia. 

Important Points

• Newton's first law of motion states that an object at rest remains at rest and an object in motion remains in motion with the same velocity unless acted upon by what we call an unbalanced force which is also called the Principle of Inertia.

• An astronaut who has their screwdriver knocked into space will see the screwdriver continue on at the same speed and direction forever.
• An object at rest stays at rest.

Additional Information

• Newton's Second Law of motion also called Law of Force and Acceleration states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force. ie., F=ma where F is the force applied, m is the mass of the body, and a, the acceleration produced.
• Newton's third law states that every action has an equal and opposite reaction. 
• An example of Newton's third law of motion is when you jump your legs apply the force to the ground and the ground also applies the opposite force to your legs which propels you into the air.

The correct answer is ​all the four valence electrons are bonded to each carbon atom by covalent bonds.

Important Points

• In diamond, each carbon atom is sp3 hybridized and linked to four other carbon atoms tetrahedrally by covalent bonds.
• As the atoms are held firmly by covalent bonds, therefore, diamond is the hardest substance.
• This results in a very big three-dimensional polymeric structure in which the C - C distance is 154 pm and the bond angle is 109.5°.
• Owing to very strong covalent bonds by which atoms are held together.
• The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on the earth.
• Hardness.
• Low coefficient of friction.
• High thermal conductivity.
• High electrical resistivity.
• Low thermal expansion coefficient.
• High strength.
• Broad optical transparency from ultraviolet to infrared.
