Topic: Pronoun (সর্বনাম),

Best Answer Explained in Below-:

The correct answer is B) Myself, as it is the emphatic pronoun in the sentence. Emphatic pronouns are a specific type of pronoun used to emphasize a noun or another pronoun in a sentence. They often serve to highlight the subject's involvement in the action, creating a stronger meaning.

In the sentence "I wash myself, when I get up in the morning," the word "myself" is used to underline that the subject "I" is performing the action of washing on themselves, rather than someone else. This conveys a sense of personal responsibility and involvement in the action.

Other options in the list do not qualify as emphatic pronouns: "wash" is a verb, "when" is a conjunction indicating time, and "morning" is a noun referring to a specific time of day. Therefore, "myself" is the only emphatic pronoun present, effectively emphasizing that the speaker is taking action upon their own self. This distinction makes "myself" the correct choice in this exercise.
