Answer:

The correct answer is 4 substracting hydride ions from olefins.

Explanation:

The olefins are the unsaturated hydrocarbon also called alkenes that contain one double bond present between 2 carbon atoms.

   On the other hand a carbenium ion is formed when a hydrocarbon loses a hydride ion to form a positively charged product.

  For example allyl cation

               CH2=CH-CH2+

The allyl cation is a carbenium ion formed by the removal of H- ion or hydride ion from the alkene propene.
