B Correct answer
Explanation

High level nuclear waste 

High level radioactive waste are the highly radioactive materials that produced as a byproduct of the reactions that occur inside nuclear reactor. Spent fuel and obsolete nuclear weapons are example of high lever nuclear waste.

Stainless steel contains:

  1. Cu and Zn

  2. Cu and Sn

  3. Pb and Sn

  4. Fe, C, Cr and Ni
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Stainless steel is a metal alloy made up of steel mixed with elements such as chromium, nickel, molybdenum, silicon, aluminium, and carbon. 


Iron mixed with carbon to produce steel is the main component of stainless steel. Chromium is added to make it resistant to rust.
