Answer 1

Answer:

The present perfect continuous tense (also known as the present perfect progressive tense) shows that something started in the past and is continuing at the present time. The present perfect continuous is formed using the construction has/have been + the present participle (root + -ing).

For the first blank, we are looking into something that has started happening and is still continuing. If we look into the formula Option A seems to be the correct answer.

The present perfect tense is used to describe something that happened in the past, but the exact time it happened is not important. It has a relationship with the present.

Have/has + past participle makes the present perfect.

In this second half of the sentence, we are looking into something that has always been there (Want to got to new work) which means we supposed to use the present perfect form. Now since, the whole sentence is in the first person, we would be using "have" and not "has".

("have" is used in case of first and second person framed sentences.)

Now, for the past participle, it the form of a verb, typically ending in -ed in English, which is used in forming perfect and passive tenses and sometimes as an adjective. In this case the past becomes, "finished".

Option A is correct
