{'manganese dioxide': [0, 0, 1, 1], 'oxide': [3, 0, 1, 2], 'cobalt': [0, 0, 0, 1], 'chromium': [2, 1, 9, 1], 'cuprous oxide': [0, 0, 1, 1], 'colour': [11, 6, 13, 28], 'green': [4, 0, 4, 6], 'violet': [2, 1, 3, 3], 'glass': [0, 0, 1, 4]}

The question asks us to match substances added to different colors imparted to the glass. Let`s dissect each option to find the correct combination.

Option 1:

This option suggests that Chromium (III) oxide imparts the color Violet to the glass, Cobalt (II) oxide imparts the color Red, Cuprous oxide imparts the color Blue, and Manganese dioxide imparts the color Green.

This option is not correct because the given color descriptions are incorrect.

Option 2:

This option suggests that Chromium (III) oxide imparts the color Red to the glass, Cobalt (II) oxide imparts the color Violet, Cuprous oxide imparts the color Green, and Manganese dioxide imparts the color Blue.

This option matches the given colors correctly.

Option 3:

This option suggests that Chromium (III) oxide imparts the color Green to the glass, Cobalt (II) oxide imparts the color Red, Cuprous oxide imparts the color Blue, and Manganese dioxide imparts the color Violet.

This option is not correct because the given color descriptions are incorrect.

Option 4:

This option suggests that Chromium (III) oxide imparts the color Violet to the glass, Cobalt (II)
