I had been asked this question in my homework.

The question is from Properties of Molding Sands topic in portion Molding and Core Sands of Casting-Forming-Welding I

Answer 1

Right choice is (d) Ability to retain hardness

The best explanation: For a mould to be having an adequate amount of green strength, it must have retaining ability or the ability to get distorted or to collapse. A mould having adequate green strength does not have the ability to retain hardness.
