POF is readily accessible unencumbered funds.
an FD is a financial instrument that is basically a guarantee by a financial institution that if you hold that deposit with them for a certain time frame you will reap the benefits set out in the signing contract.
what you need to show effectively, if asked is that the money is yours, it was earned or saved by you and if it was gifted to you then there is a gift deed and you do not have to give it back.
the fact of having an FD is irrelevant as the FD can be broken anytime you need to and in situations where you have to pay a penalty the penalty is a minimum amount and does not significantly affect your savings.
did somebody else made that FD for you?
can you conclusively show that the money in question belongs to you?
can you show the history of the money in question?
these are the questions which need to be answered.
