Identify the correct Passive Voice form of the following sentence:-

'Her colleagues laughed at her".

She was laughed at by her colleagues.

The correct answer is Option (4) → She was laughed at by her colleagues.

Here's why:

• The original sentence is in the active voice, where "Her colleagues" (the subject) perform the action "laughed" on "her" (the object).
• In the passive voice, the focus shifts to the object (the one receiving the action).
• So, "She" becomes the subject in the passive voice, and "her colleagues" becomes the agent performing the action, introduced by "by."
