text: mujhe samajh nahi aa raha,retirement ke liye best investment option kya hai, kya tu mujhe kuch suggestions de sakti hai, kyunki main confused hoon!public provident fund (ppf) aur national pension scheme (nps) achhe options hain, kyunki yeh government backed hote hain aur tax benefits bhi milte hain, so inhe consider karna chahiye!
