Final answer:
In the sentence 'Sunil washed his shirt himself,' the underlined pronouns are 'his' (a possessive pronoun) and 'himself' (a reflexive pronoun). 'His' indicates Sunil's ownership of the shirt, and 'himself' indicates that Sunil is performing the action on himself.
Step-by-step explanation:
The sentence provided is "Sunil washed his shirt himself." In this sentence, the pronouns that need to be underlined are "his" and "himself." The pronoun "his" is a possessive pronoun, which is used to show ownership or relation to Sunil, indicating that the shirt belongs to Sunil. The pronoun "himself" is a reflexive pronoun, which is used as an object that refers back to the subject, Sunil, who is also performing the action.
Reflecting upon the nature of reflexive pronouns, they must end in -self or -selves, signifying that the action of the verb is being done to the same subject. "Himself" meets this condition as it reflects the action of washing back onto the subject. Therefore, the correct answer to the provided question is "Sunil, himself (Reflexive pronoun)."
