Which of the following reduce email emissions? Choose all that apply.a.Unsubscribing to unnecessary emailsb.Deleting Archived Mailc.Blocking spamd.Sending attachments instead of links to shared docs

The options that reduce email emissions are:

a. Unsubscribing to unnecessary emails: This reduces the number of emails sent to your inbox, which in turn reduces the energy used to process, store, and send these emails.

c. Blocking spam: Similar to the first option, this reduces the number of unnecessary emails sent to your inbox.

The other options do not necessarily reduce email emissions:

b. Deleting Archived Mail: While this might free up storage space in your email account, it doesn't necessarily reduce the energy used to process emails. The emails have already been sent and stored, so the energy has already been used.

d. Sending attachments instead of links to shared docs: This could actually increase email emissions. Attachments increase the size of an email, which requires more energy to send. Sending a link to a shared document is more efficient because it requires less data to be sent.
