Hint: We know that Electronic waste, likewise called e-waste, different types of electric and electronic gear that have stopped to be of worth to their clients or presently don't fulfill their unique reason. Electronic waste (e-byproducts) have depleted their utility worth through one or the other excess, substitution, or breakage and incorporate both "white merchandise" like fridges, clothes washers, and microwaves and "earthy colored products" like TVs, radios, PCs, and cells.
Complete solution:
E-waste is one of the quickest developing waste streams. Despite the fact that e-waste contains complex blends of profoundly poisonous substances that represent a peril to wellbeing and the climate, large numbers of the items additionally contain recoverable valuable materials, making it an alternate sort of waste contrasted and customary metropolitan waste.
The wellsprings of e-waste are broken PCs, links, printers, fridges, climate control systems, TVs, electronic and electrical gadgets. E-waste created by the Mobile Phones is copper, silver, gold, palladium. Among them copper is found richly. Hence option A is correct.
Note:
The current substitution of electronic items is accelerating, bringing about a developing number of e-waste. Electronic waste, particularly waste printed circuit sheets contain a lot of copper, which bring more prominent environmental danger, yet additionally aim a genuine misuse of copper assets. Hydrometallurgical is a superior innovation for reusing copper from waste printed circuit boards. The benefits and disservices of draining copper framework are investigated during the time spent copper asset use. Studies flourish on reusing copper from copper-containing waste with citrus extract and other complexing specialists as the filtering reagent, yet concentrates on reusing copper from waste printed circuit sheets are once in a while revealed, which can be utilized for reference. The patterns of the examination are utilizing harmless to the ecosystem reagent as draining specialist, choosing the fitting filtering arrangement at a specific temperature and pressure and advancing the ensuing division strategy. Reusing of waste gas and waste leach created in the hydrometallurgical process can further decrease compound expenses and meet progressively demanding natural necessities.
