Step-by-step explanation:

Answer 2

C, the demand for the precious metals has increased and technological advances allow the metals to be extracted more efficiently.

Step-by-step explanation:

Because cellphones today make use of certain precious metals in the production of bespoke editions, luxury editions and other high class editions, these cell phones are recycled and the precious metals are taken off them to produce other cellphones or human wants as the precious materials are durable and hardly get destroyed like other materials used in producing cellphones. Gold for example is commonly used for some high end cell phones and because gold never goes bad, it can be recycled and the gold extracted from a bad cellphone along side other metals to produce other cellphones or another human want. Technology today has helped in the extraction of these metals from these cell phones totally and purely for use for other things.

Cheers.
