Question 3: What is the past tense of place?

Placing
Plasis
Plased
Placed (Correct answer)

Correct answer: Placed

The past tense of the verb "place" is "placed". This is the correct answer because when we want to talk about an action that happened in the past, we use the past tense form of the verb. In this case, "placed" is the correct past tense form of "place".

'She' should be 'Her'
