Answer 1

Right choice is (d) High-nickel alloys, iron-chromium alloys, and brasses

Explanation: Stress-corrosion cracking can be intergranular and trans-granular cracking. Alloys such as high-nickel alloys, iron-chromium alloys, and brasses often crack both in intergranular and transgranular manner.
