Hint: The student should go through the options carefully after reading the sentence to understand what the sentence implies. This will help the student in finding the right answer for the given question.

Complete answer: An adjective is a word that expresses an attribute of something. It is the word class that qualifies nouns. Some adjectives are - beautiful, sweet, delicious, odorous, tingly.
Let us thus analyze the options given to us in this question -
Option (a.), 'True', refers to ‘mouth-watering’ as a compound adjective.
Therefore, option (a.) is correct as compound adjectives are often distinguished with hyphens to prevent ambiguity. A compound adjective is formed from two or more adjectives. These together modify the same noun.
Option (b.), ‘False', refers to ‘mouth-watering’ as NOT a compound adjective.
Therefore, option (b.) is incorrect as mouth-watering is indeed a compound adjective since compound adjectives are often distinguished with hyphens to prevent ambiguity (unclearness by virtue of having more than one meaning).
Thus, option a is correct.

Note: In this question, it will be helpful for the student to recall the concept of compound adjectives. A compound adjective is made when two or more adjectives are joined together to modify the same noun. Some examples of compound adjectives are - part-time, cold-blooded, brightly - lit, seven-foot.
