All the options are FALSE.
Option A is NOT the definition of a quantum computer. A quantum computer is a computer that exploits the quantum mechanical properties for computation. Moreover, simple common sense tells you this is very stupid way of defining what a quantum computer shall be !!
Option B is also FALSE because a supercomputers’ performance is defined in terms of FLOPS. Refer this to know more.
Option C is FALSE, again you can see why, simple calculation
I suppose option D had been ALL THE ABOVE instead of NONE OF THE ABOVE
