Directions: A sentence is given here with a blank and you need to fill the blank choosing the word/words given below. If all the words given can fill the blank appropriately, choose ‘All are correct’ as your answer. Being a parent is stressful but _______ , and in order to be a good parent you must make good children. I. rewarding II. demanding III. fulfilling

Step-by-step solution

Here, the connecter between ‘stressful’ and the blank is ‘but’ which clearly implies that two words with opposite meaning must be there. ‘Demanding’ is a synonym of ‘stressful’ and therefore can be eliminated. Both ‘rewarding’ and ‘fulfilling’ are synonyms and both are antonyms of ‘stressful’. Clearly, option B is the correct answer.
