Select the option that expresses the given sentence in present perfect continuous tense form
Rama is working on this project.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Rama has been working on this project for six months.
Present perfect continuous tense = has/have + been + verb(-ing), used for actions that started in the past and are still continuing.
-
Option 1 is correct and grammatically accurate.
-
Option 2 is present perfect tense, not continuous.
-
Option 3 is wrong because “since six months” should be “for six months.”
-
Option 4 mixes present continuous with a time period, which is incorrect.
Hence, the chosen option is correct.
