• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The correct option is A

The explanation of the correct option:

A:

Grignard Reagent:

• An organomagnesium molecule known as a Grignard reagent has the chemical formula $\mathrm{R}-\mathrm{Mg}-\mathrm{X}$, where $\mathrm{R}$ stands for an alkyl or aryl group and $\mathrm{X}$ for a halogen.
• They are typically created by reacting magnesium with an aryl halide or an alkyl halide.
• In the above given reaction Grignard Reagent is used as ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{MgBr}$, and the above reaction is gone firstly by Grignard reagent and then it is hydrogenated.
• 

Final Answer: Therefore, Option A is the correct option.
