Select the correct indirect form of the given sentence.
Madhurima explained, “I am planning to quit my graduation.”

Correct option is C

Direct speech is the use of the exact words spoken by someone, enclosed in quotation marks.
Indirect speech (also called reported speech) is when we report what someone said without necessarily using their exact words. In indirect speech, we use a reporting verb to introduce the speaker's words and often have to change the tense and some of the words in the original sentence.
 In indirect speech, the tense of the reporting verb is usually shifted back one tense, and the pronouns are also changed accordingly. In this case, "I am" should be changed to "she was" to maintain the past tense.
 The correct option is (c) because it uses the correct past tense of the reporting verb and changes the pronoun "I" to "she".
 The correct indirect form of the given sentence is: option (c) Madhurima explained that she was planning to quit her graduation.
