A collision is the event in which two or more bodies exert forces on each other in about a relatively short time.
Thus, by this definition, it is clear that the interaction time is very short, hence tint<<tsys.
Also, the major forces are the forces that the body exert on each other and hence, Fext<<Fint.
The conservation of momentum holds in both elastic and inelastic collisions. Hence
While the change in Kinetic energy is zero for elastic
collisions, it is not so for inelastic collision. Thus
for collisions in general.
So, option (1) (2) and (3) are correct.
