Balmer, in His Home-Made Will, Leaves All His Property to Be

Balmer, in his home-made will, leaves all his property to be held by Judas, his trustee, 'in the hope and expectation that he will distribute it to such of my blood relatives who survive me, as Judas in his absolute discretion shall decide, or in default of appointment, everything should be given to my nephew, George.'
Balmer has sought to create:

A) A fixed trust for named beneficiaries.
B) A mere power, under which Judas can either chose to distribute the pieces of crystal, or keep them for himself.
C) A discretionary trust.
D) A fiduciary power.
