Answer:
The white dwarf will explode completely as a white dwarf supernova.
Explanation:
When a white dwarf gains mass to the Chandrasekhar limit of 1.44 solar masses, it would begin to collapse and, in a few seconds, the matter in the white dwarf will undergo nuclear fusion, and will become in a supernova.
Only when the core of the white dwarf is composed of neon, magnesium, and oxygen, the gaining mass to 1.44 solar mass, will result in a neutron star.
Therefore, the answer is the white dwarf will explode completely as a white dwarf supernova.
