I hope this helps!
The correct answer is D, this is 'present perfect' tense. It is formed with the use of the verb HAVE in present simple tense (so, HAVE/HAS), and the past participle of a verb (or the third column of irregular verbs).
A cannot be correct, because then it would say - I hear.
B cannot be correct, because then it would say - I had heard.
C cannot be correct, because then it would say - I heard.
And since there is also HAVE HEARD, the correct answer has to be D.
Answer:
1. Present tense
2. Past tense
3. Future tense
Explanation:
1. The sentence "I am a boy" is in the simple present tense (indefinite).
We often use Simple Present to talk about timeless truths/facts or permanent situations. We don't say, "I'm being a boy" or "I've been a boy".
2. If you are unable to determine the tense of a sentence immediately, you can use context clues too. In this sentence, "gave" is the past tense of "give", we can tell that this sentence is in the past tense because the child's parents gave them money (at some other time).
3. If you still struggle to identify the tense of a sentence, try to place yourself in the given situation. If you "will buy the book of UAE history as well" you are going to buy it, "will" is the indicator here, you have not "bought" the book yet, and you are not currently buying it, so you WILL buy it.
