Suit against which of the following is NOT barred by period of limitation?

Under section 10 of the Limitation Act, 1963 no period of limitation applies to a suit against a person in whom property has become vested in trust for a specific purpose, or against his legal representatives or assigns (other than assigns for valuable consideration), to follow that property or its proceeds or for an account of it; so the answer is "Trustee". Suits against a tenant, a debtor or a partner are governed by the ordinary periods in the Schedule.
