In this question, we are given a list of metallic oxides in List I and a list of colors imparted to glass in List II. We need to match the correct metallic oxide with the corresponding color imparted to glass.
Looking at List I, we have the following metallic oxides:
A. Uranium oxide
B. Cuprous oxide
C. Cobalt oxide
D. Chromium oxide
In List II, we have the following colors:
1. Red
2. Blue
3. Green
4. Yellow
Now, let`s look at the correct answer, which is option 1: 4-1-2-3.
According to this answer, Uranium oxide imparts a yellow color to glass, Cuprous oxide imparts a red color, Cobalt oxide imparts a blue color, and Chromium oxide imparts a green color.
Therefore, based on the correct answer, the matching is as follows:
A. Uranium oxide - Yellow
B. Cuprous oxide - Red
C. Cobalt oxide - Blue
D. Chromium oxide - Green
So, option 1 is the correct answer.
Note: The given answer is generally correct. However, it is important to note that different metallic oxides can impart different colors
