Best answer
Correct choice is (a) True

Easy explanation: In vacuum die casting, the components which are casted do not experience any porosity due to the removal of all the air from the cavity. The castings made have negligible porosity as compared to the castings made by die casting. So, the castings are of high strength in the vacuum die casting.
