PF money you can show. For that you need to take the latest statement from EPFO site, and also provide a LOE that the funds belong to you, and the entire funds will be available for withdrawal after you quit your job. You can also request your company HR to provide you such a letter since they are managing your PF account. Get the letter notarized.
As for Mutual Funds, you may have to sell off those units and get the money in your bank account. CIC specifically mentions, that the POF should be readily available in the bank account. The reason they don't accept MF statements as POF cos the funds are still linked to the market and subjected to market risks.
PPF - This one is also tricky as PPFs have lock-in periods, and you cannot withdraw them prior to maturity. You might have to check with others on the forum as to how one can use PPF.
