Correct option is D
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.
· To convert the given sentence "Professor told me that I could not rescue myself from that bait" into direct speech, we need to remove the reporting verb "told" and change the tense of the reported speech to match the time of the reporting verb.
· We also need to remove the conjunction "that" and put the reported speech in quotation marks.
· Applying these steps, the correct direct form of the sentence is "Professor said to me, 'You cannot rescue yourself from this bait'."
