Hint:The student should pronounce each word individually and check which combination of the words in the options given in the questions sounds similar by paying attention to the sound of the ending of the word.

Complete answer: In this question, it will be helpful for the student to recall the concept of homonyms. Two words are homonyms if they are pronounced or spelt the same way or both but have different meanings.
Let us analyze the options given to us in this question -
Option (a.), 'dart, mark', refers to ‘dart’ which means ‘run or move very quickly or hastily’ and ‘mark’ which means ‘attach a tag or label to’.
Therefore, option (a.) is incorrect as ‘dart’ ends with ‘art’ and ‘mark’ ends with ‘ark’ which is not similar sounding at all.
Option (b.), ‘ajar, star', refers to ‘ajar’ which means ‘to turn or open slightly; to become ajar or to cause to become ajar; to be or to hang ajar’ and ‘star’ which means ‘a celestial body of hot gases that radiates energy derived from thermonuclear reactions in the interior’.
Therefore, option (b.) is correct as ‘ajar’ ends with ‘ar’ and ‘star’ ends ‘ar’ which is similar to sounding.
Option (c.), ‘care, star', refers to ‘care’ which means ‘the work of providing treatment for or attending to someone or something’ and ‘star’ which means ‘a celestial body of hot gases that radiates energy derived from thermonuclear reactions in the interior’.
Therefore, option (c.) is incorrect as ‘care’ ends with ‘are’ and ‘star’ ends with ‘ar’ which are pronounced differently.
Option (d.), ‘care, mark', refers to ‘care’ which means ‘the work of providing treatment for or attending to someone or something’ and ‘mark’ which means ‘attach a tag or label to’.
Therefore, option (d.) is incorrect as ‘care’ ends with ‘are’ and ‘mark’ ends with ‘ark’ which are pronounced completely differently.
Therefore, option (b) is correct.
