Fill in the blank with a suitable option:
“Would you like to come to my part?”
He invited her _ _ _ _ _ _ _ _ _ _
(a)She’d like to come to his party
(b)She’d like to come to my party
(c)If she’d come to his party
(d)To come to his party

Hint: The given sentence we have is in direct speech. The speaker’s exact words have been quoted here. The second one with a blank to fill is indirect speech. The exact meaning is expressed in indirect speech but not necessarily in the exact words.

Complete answer:
When the speaker’s exact words are quoted and delivered to a third person then we call it direct speech, For example, He said, “I work in a big firm.”
When the words of the speaker are delivered to a third person without altering the core meaning but not quoting them exactly, it is called indirect speech. For example, He told that he worked in a big firm. Half of the sentence's direct words have been given to us i.e., “He invited her..” When we turn direct questions and exclamations into indirect speech, they are converted to an affirmative statement. (? and ! is not used). Now let us look at the options we have and choose the option which completes the sentence.
Option a “She’d like to come to his party” is incorrect as if this phrase follows the one that precedes it i.e., “He invited her” then it would not be a complete sentence as conjunction would be required to join the two clauses. Also, the meaning of direct speech would change. Thus, option ‘a’ is incorrect.
Option b “She’d like to come to my party” and ‘c’ “If she’d come to his party” are both incorrect. Firstly, because the meaning of the direct speech would be altered with these two options and secondly, in option ‘b’ ‘my’ has not to be changed into a third-person pronoun. Thus, both the option ‘b’ and ‘c’ is incorrect.
Option d ‘to come to his party.’ Is the correct option as it retains the core meaning of the sentence is direct speech? All the first-person pronouns have been changed to third-person pronouns.

Thus, the option ‘d’ is the correct answer.

Note: For changing direct speech into indirect speech, Omit all inverted commas or quotation marks. End the sentence with a full stop. If the verb inside the inverted commas/quotation marks is in the present tense, change it into the corresponding past tense. If it is in the simple past tense, change it into the past perfect tense.
