Convert the sentence provided below from its passive voice structure to an active voice structure: The package is delivered to the office every morning.

Correct — B. The verb is delivered is simple present passive, and the sentence names no doer: there is no by-phrase.

An active sentence needs a subject, so an indefinite one stands in, Someone. The tense stays simple present, delivers, and the package becomes the object.

To the office and every morning carry over unchanged. That gives "Someone delivers the package to the office every morning" — option (b).

Why the others are wrong

• (a)
  The office delivers the package every morning. — The office delivers turns the destination into the doer. In the passive the office only receives the package, and this version also drops to.
• (c)
  The office has delivered the package every morning. — has delivered changes the simple present into the present perfect, and it makes the office the doer. Both the tense and the roles are wrong.
• (d)
  The package delivers itself to the office every morning. — delivers itself makes the package its own doer. In the passive the package is what gets delivered, not what does the delivering.

Passive to active reverses one move: the doer returns to the subject slot, and the passive subject becomes the object.

When the passive names no doer, the active takes an indefinite subject — someone, somebody, people or they — rather than a specific agent the sentence never mentioned.

The form of be sets the active tense: is delivered → delivers, was delivered → delivered.

Key facts

• Simple present passive: is/are + past participle (is delivered).
• Its active counterpart is the simple present: delivers.
• A passive with no by-phrase takes an indefinite subject in the active: someone, people, they.

Common traps

• Picking the office as the doer because it is already in the sentence
• Changing is delivered to has delivered, when the active keeps the simple present
