Answer:
A. politer
Step-by-step explanation:
An adjective is one of the parts of speech in English language and it can be defined as a word that qualifies or describes a noun in a sentence. Some examples of an adjective are big, small, happy, tall, short, fat, rambunctious, etc.
In English language, there are three (3) forms of adjectives and these includes;
I. Positive adjectives: it is the simplest form of an adjective that expresses the quality of a physical object, person, place, etc., without comparison.
II. Superlative adjectives: it is used to show that a person or thing has a greater degree of quality than two or more other persons or things. Thus, it is used for comparing three or more people, things, place, etc.
II. Comparative adjectives: it is used for comparing two things, person or place. Signal word such as more is used for comparison or the suffix "er" is added to the adjective.
In English language, politer is simply a comparative form of polite and it implies showing respect for the feelings of other people.
Hence, the sentence would be written and paragraphed as;
Speaker A: Don't forget to say "please" when you want something from someone, dear. It is politer.
Speaker B: I understand, mum.
