Hello, I would appreciate some help with this question, thank you!

 
Step 1 (reduce ketone to alcohol):

NaBH₄, MeOH (or LiAlH₄, then workup)
Gives 2-propanol
Step 2 (dehydrate alcohol to alkene):

conc. H₂SO₄, heat (or POCl₃/pyridine for a cleaner dehydration)
Gives propene

Step 3 (make alkyne from alkene):
1) Br₂ (CCl₄ or CH₂Cl₂) → vicinal dibromide
2) excess NaNH₂, liquid NH₃ (typically 2–3 equiv) → double elimination
3) H₂O / NH₄Cl workup
