Which of the following is a method for the preparation of alkenes?

Step 1: Understand that alkenes are hydrocarbons with at least one double bond between carbon atoms.
Step 2: Know that alkyl halides are compounds that contain carbon, hydrogen, and a halogen (like chlorine or bromine).
Step 3: Learn about dehydrohalogenation, which is a chemical reaction that removes a halogen and a hydrogen atom from an alkyl halide.
Step 4: Realize that when you remove these atoms, a double bond is formed between the carbon atoms, resulting in an alkene.
Step 5: Remember that this method is commonly used in organic chemistry to synthesize alkenes.
