The correct answer is A. 12543.
The word “delay” means to postpone or put off something. The word “don’t” is a negative word that means “do not.” The word “make” means to create or produce something. The word “please” is a polite word that means “I ask you to do something.” The word “further” means to a greater extent or degree.
In the sentence “Please don’t delay further,” the word “delay” is used in the sense of “postpone.” The word “don’t” is used to make a request more polite. The word “please” is used to make a request more polite. The word “further” is used to emphasize the need to act quickly.
The other options are incorrect because they do not make sense in the context of the sentence. Option B, “32541,” is incorrect because the word “make” does not make sense after the word “don’t.” Option C, “25314,” is incorrect because the word “please” does not make sense after the word “delay.” Option D, “42351,” is incorrect because the word “further” does not make sense after the word “make.”
