A transfers property to B in trust for C and directs B to give possession of the property to C when he attains the age of C’s interest in the property is

The correct answer is (a) Contingent.

A contingent interest is an interest in property that is not certain to vest. In this case, C’s interest in the property is contingent on him attaining the age of 25. If C dies before he reaches the age of 25, his interest in the property will lapse and will not pass to his heirs.

A vested interest is an interest in property that is certain to vest. In this case, if C reaches the age of 25, his interest in the property will vest and he will be able to take possession of the property.

Neither contingent nor vested is not a valid option.

Public interest is not a relevant factor in determining whether C’s interest in the property is contingent or vested.
