Q1. Choose the correct form of the verb or tense to complete the sentence from the given options: "The child ................ for the last one hour."
A has been sleeping Correct
B slept
C is sleeping
D was sleeping
Explanation
The phrase "for the last one hour" shows an action that began in the past and continues up to the present. The present perfect continuous form "has been sleeping" correctly expresses that duration. "Slept" is simple past and treats the action as finished. "Is sleeping" shows a present action but does not carry the past-to-present duration properly. "Was sleeping" places the action in the past continuous and does not connect it with the present moment. The sentence therefore requires the present perfect continuous tense.
