**Propose an Efficient Synthesis for the Following Transformation:**The chemical transformation depicted involves the conversion of an aromatic ring with a single substituent into an aromatic ring with a propargyl substituent (adjacent alkyne group).The transformation can be performed with a sequence of reagents listed below. Provide the necessary reagents in the correct order as a continuous string of letters (without spaces or punctuation, e.g., “EBF”). If multiple correct solutions are possible, provide only one answer.A. NBS, heat B. NaOEt C. HBr, ROOR D. HBr E. conc. H₂SO₄, heat F. HC≡CNa Consider the mechanism of each step and select the appropriate reagents to achieve the desired transformation.

NBS is specifically used for bromination at allylic or benzylic position. Sodium ethynide acts as…
