Topic: Pronoun (সর্বনাম),

Best Answer Explained in Below-:

In the sentence provided, the context involves Pinocchio seeking to cook an omelet. The word that fills the blank should logically refer back to Pinocchio as the subject of the action. The correct answer, "himself," is a reflexive pronoun that emphasizes the subject's involvement in the action.

Let’s analyze the options:

- **A) His own self** is redundant and overly formal in this context.
- **B) Itself** refers to an inanimate object, which does not apply here since it would suggest the omelet possesses autonomy.
- **C) Oneself** is a more general term that implies a broader meaning, distancing itself from the specific subject, Pinocchio.
- **D) Himself** correctly refers to Pinocchio, making it clear that he is the one performing the action of cooking.

Using "himself" establishes a direct relationship between Pinocchio and his actions, fitting seamlessly with the narrative that he intends to cook for his own benefit. Thus, "himself" is the most appropriate choice, conveying both the subject's involvement and maintaining clarity in the sentence structure.
