Answer:
Answer B is the correct answer: "<em>Motion of one projectile as seen from the other is a straight line.</em>"
Explanation:
Let's write the equations of motion for each projectile, using that projectile
is launched with velocity
which has components associated with the angle of launching, given in x and y coordinates as:
.
Similarly, assume that projectile b is launched with velocity
with components due to the launching angle = 
then the equations of motion for the two projectiles launched at the same time (t) from the same spot (position that we assume to be at the origin of coordinates to simplify formulas) are:

therefore, from the frame of reference of projectile "b", the x and y position of projectile "
" would be:
which is linear in "t"
which is also linear in t.
Therefore the motion of one projectile with reference to the other is a straight line (answer B)
Notice as well that this two projectiles cannot collide because they have been launched together, and supposedly at different speeds and angles. The only way that they can share the same x-coordinate and the same y-coordinate at the same time "t" is if their velocity components are equal, which is not what we are told.

The action-reaction pairs in the given situation are:
- the backpack and the bench
- the and and the wall
<h3>What are action-reaction pairs?</h3>
Action-reaction pairs are two forces which are equal but oppositely directed in their line of action.
Action-reaction pairs are according to Newton's third law of motion.
