The question was asked in semester exam.

My doubt stems from Permanent Mould Casting in division Special Casting Techniques of Casting-Forming-Welding I

Answer 1

Right answer is (a) True

The best I can explain: The gating and risering systems used in the permanent mould casting are very similar to that of the sand casting. In fact, to get the proper gating arrangement, it is desirable first to experiment with various gating systems in sand casting and then finally arrive at the correct gating system for the metallic mould.
