Question

Choose the correct alternative of the verb given in brackets.
She _____ (work) since morning and now she wants to take a rest.
A. Has been working
B. Had working
C. Was working
D. Had worked

Answer 1

Hint: The sentence suggests that ‘now she wants to take rest’ that implies due to some action in the past involving the verb ‘work’ and individual needs to rest in the present. In such a case where due to action happened in the past, the effect is felt in the present, we use present perfect continuous tense. It comprises two elements: the present perfect form of the verb ‘to be’ which is has been or have and the present participle of the main verb.
Example: The students have been practicing the dance for hours, now they need to rest.

Complete step by step answer:
Let us analyze each option in detail to know the correct answer.
Has been working: By implying this option, the sentence becomes ‘She has been working since morning and now she wants to take rest’. This completes the sentence in a complete and correct way. Here, the present continuous form of the verb ‘to be’ used is ‘has been’ and the present participle of the main verb ‘work’ used is working. Therefore, this is the correct option.
Had working: By implying this option, the sentence becomes ‘She had worked since morning and now she wants to take rest’. This sentence is grammatically incorrect as the past perfect form of ‘to be’ is had and it is used with the verb ‘working’ without the word ‘ been’. Therefore, this is an incorrect option.
Was working: By implying this option, the sentence becomes ‘She was working since morning and now she wants to take rest’. The past continuous form ‘was working’ doesn’t justify the effect of the action ‘now she wants to take rest’. Therefore, this is an incorrect option.
Had worked: By implying this option, the sentence becomes ‘She had worked since morning and now she wants to take rest’. This form is in the past perfect tense, therefore this is an incorrect option.

So, the correct answer is “Option A”.

Note:
The subject ‘She’ here, is a singular noun, therefore, the present continuous form of the verb ‘to be’ will be ‘has been’. Also, a present continuous form describes an action that was started in the past and is still continued in the present. Example: She has been working since morning.
