Question

Identify the tense used in the following sentence:
They will have been writing their letters.
A. Future Perfect Continuous
B. Future Continuous
C. Present Perfect Continuous
D. Present Perfect

Answer 1

Hint: Tense is a verb that explains the action of a person when he/she does something. There are three types of tenses known as past, present and future tense. Have been is used for an action that started in the past, but continues in the present.

Complete answer:
Future perfect continuous shows that the event will continue up until a particular time in the future. For example- In August, I will have been working at my gym for three years. Future continuous tense is used to discuss future events that will take place in future. For example- Sita will arrive at six o'clock. Therefore,
Option A and Option B are incorrect options as they talk about the future and the action is taking place at present. Present perfect continuous tense is used to describe an event started in the past and has continued up till now.
According to the question, Present perfect continuous is the right answer because they started writing their letters in the past and continued writing till now.

Hence the correct answer is option C

Note:
Have been is used in both Future perfect continuous tense and present perfect continuous but there is a huge difference as future perfect continuous tells about the continuity of the event till a particular time period but in present perfect continuous it doesn’t.
