Option F is correct i.e. it's FALSE.
Lets see how.
When a star dies it has three possibilities
1. White dwarf
2. Neutron star
3. Black hole
When core mass is < 1.4 Msun then white dwarf and when core mass>1.4 Msun, then supernova and hence neutron star. When core mass>3 Msun, the black hole.
So a white dwarf can produce a a supernova as a white dwarf is very hot when it forms, but because it has no source of energy, it will gradually radiate its energy and cool and then it called as a dark or black dwarf star. But it can be, if it's part of a binary system, then it can accrete mass and then explode in one as tupe Ia supernova.
So option F is false that a white dwarf can produce a supernova. But remember it can if it's a part of binary system.
