For your first statement:
True - According to Newton's First Law of Motion, an object in motion will remain in motion at a constant velocity (in a straight line) unless acted upon by a net external force.
For the second question regarding examples of Newton's First Law:
The correct answer is:
c - A stationary book on the table must be picked up in order for it to move.
This illustrates the concept that an object at rest will remain at rest until acted upon by an external force. The other options describe different physics principles or laws.
