According to the collision theory, what happens in a collision without sufficient energy or correct orientation

Hi!

In collision theory, for a chemical reaction to occur - there must be sufficient energy to break down chemical bonds.
 
We call this the activation energy, as it's the energy needed to activate a chemical reaction! 

Hopefully, this helps! =)

There won't be a substantial change or effect if the collision does not meet the requirement. Hope this helps!

The correct answer is b.hoped i you
