<h3>The comparative form of adjectives</h3>
The comparative form of adjectives is used, as the name suggests, when we compare different things or people. Some simple rules must be kept in mind when making comparisons:
Short adjectives receive the ending -er: smaller, faster, older.
If the short adjective ends in consonant + vowel + consonant, we must double the final consonant: hotter, bigger.
Two-syllable adjectives ending in -y can use both forms: heavier or more heavy.
Adjectives that have two or moresyllables must come after "more": more intelligent, more attractive.
Adjectives "good" and "bad" have their own forms: better and worse, respectively.
With the information above in mind, we can conclude the answer provided above is correct.
