The sentence in the past continuous tense is: c) She was singing when I entered the room.

The past continuous tense is used to describe an ongoing action that was happening in the past at a specific moment or during a specific period of time. It is formed by using the past tense of the verb "to be" (was/were) and the present participle form of the main verb (ending in -ing).

Explanation:
When we analyze the given options, we can identify the sentence in the past continuous tense by looking for the verb form and its tense.

a) They have been married for five years.
- This sentence is in the present perfect tense, indicating an action that started in the past and continues up to the present.

b) We will be arriving at the airport in an hour.
- This sentence is in the future continuous tense, indicating an action that will happen in the future.

c) She was singing when I entered the room.
- This sentence is in the past continuous tense. The verb "was singing" is formed using the past tense of "to be" (was) and the present participle form of "sing" (singing). It describes an ongoing action (singing) that was happening in the past (when I entered the room).

d) He had already left before I arrived.
- This sentence is in the past perfect tense, indicating an action that occurred before another past action.

Therefore, the correct answer is option c) "She was singing when I entered the room" as it is the only sentence that is in the past continuous tense.

Explanation:

The present perfect tense is used to describe an action that happened in the past but has a connection to the present. It is formed by using the auxiliary verb "have" or "has" followed by the past participle of the main verb.

Identifying the Sentences:

Let's analyze each sentence to determine which one is in the present perfect tense:

a) She will be studying for her exam tomorrow.
This sentence is in the future tense, not the present perfect tense. It indicates an action that will happen in the future.

b) He has already eaten breakfast this morning.
This sentence is in the present perfect tense. It uses the auxiliary verb "has" followed by the past participle "eaten" to describe an action that happened in the past (this morning) but has a connection to the present.

c) They were playing tennis when it started raining.
This sentence is in the past continuous tense, not the present perfect tense. It describes an ongoing action in the past (playing tennis) that was interrupted by another action (it started raining).

d) I had finished my work before my boss arrived.
This sentence is in the past perfect tense, not the present perfect tense. It uses the auxiliary verb "had" followed by the past participle "finished" to describe an action that happened before another action in the past (my boss arrived).

Conclusion:

Out of the given options, the sentence "He has already eaten breakfast this morning" is in the present perfect tense. It follows the structure of the present perfect tense by using the auxiliary verb "has" followed by the past participle "eaten" to describe an action that happened in the past (this morning) but has a connection to the present.
