The correct answer is - গ) Demonstrative pronoun

Demonstrative Pronoun:
- ব্যক্তি বা বস্তুকে যদি এটি, ওটি, এগুলি, ওইগুলি ইত্যাদি শব্দ দ্বারা নির্দেশ করা হয় তাহলে এই শব্দগুলোকে বলে demonstrative pronoun।

Example:
- This is my favorite book.
- That was an amazing performance.
- These are freshly baked cookies.
- Those belong to my brother.
এই this, that, these, those শব্দগুলো যথাক্রমে book, cookies, belongings-এর পরিবর্তে বসে সেগুলোকে নির্দেশ করছে।
এগুলো হলো Demonstrative pronoun।

Pronoun:
- Pronoun হলো noun এর পরিবর্তে ব্যবহৃত word। এ কারণে Pronoun কে Substituting word বলা হয়।

Example:
- He, She, We, They, I, ইত্যাদি।

Pronoun ৮ প্রকার:
1. Personal Pronoun (He, I, we, me, you),
2. Demonstrative Pronoun (this, that, such),
3. Interrogative Pronoun (what, who, which),
4. Relative Pronoun (what, who, which, that),
5. Indefinite Pronoun (one, some, any, many)
6. Distributive Pronoun (each, every, either, neither),
7. Reflexive Pronoun (myself, yourself, themselves),
8. Reciprocal Pronoun (each other, one another).
