Question

Which sentence is in the active voice

Answer 1

The answer is D: Our old toaster always burns the toast on one side. This sentence is using an active verb. The other sentences are in the passive voice, which is formed by putting the verb to be into the same tense as the active verb and adding the past participle of the active verb. (A) to be: was + negotiated;  (B)to be: was+ colonized; (C) to be: was + quoted.  In the active voice, they would be:  (A) "A team...negotiated the pact."; (B) "A dazzling...colonized the garden." and (C) "A magazine quoted our teacher..."

Answer 2

Last one, about the old toaster burning toasts.
The toaster actively burns toasts. Other sentences are all 'was+V-ed'
