Answer 1

Correct answer is (a) To produce small castings in mass production

Explanation: Gated pattern manufactures huge no. of products using single time casting using a common gating inlet system. Hence, the casting needs to be small and simple and is only justified for mass production, as the pattern is used for 1-2 times only.
