Convert the sentence provided below from its passive voice structure to an active voice structure: The photos will be printed by the studio within an hour.

Correct — B. The passive verb is will be printed: will be + past participle, the simple future passive.

The active keeps the tense. Simple future active is will + base verb, so will print.

The agent after by, the studio, becomes the subject, and the photos become the object. Within an hour stays as it is: "The studio will print the photos within an hour" → option (b).

Why the others are wrong

• (a)
  The studio prints the photos within an hour. — prints is simple present. The given sentence is future, will be printed, and changing the voice never changes the tense.
• (c)
  The photos printed by the studio soon. — The photos printed by the studio soon has no auxiliary and keeps the photos first, so it is neither active nor complete. Soon also replaces within an hour.
• (d)
  The studio had printed the photos in an hour. — had printed is past perfect, which moves the action into the past. It also changes within an hour to in an hour.

Voice changes who stands where in the sentence. It never changes the tense.

Passive to active: the agent after by becomes the subject, the passive subject becomes the object, and the verb takes the active form of the same tense.

Simple future: will be printed → will print. Present perfect: has been printed → has printed. Simple past: was printed → printed.

Key facts

• Simple future passive: will be + past participle (will be printed).
• Simple future active: will + base verb (will print).
• In a passive-to-active change, the agent after by becomes the subject.

Common traps

• Picking prints because its words match, without checking that will has gone
• Accepting a changed time phrase such as soon or in an hour because the verb looks right
