Step-by-step explanation:
By adding the letter 'b' to the word 'smile', we get the word 'smileb'. However, 'smileb' is not a figure of speech. The correct answer would be either option (a) Simile, (c) Slime, or (d) Slide. These words are not a result of adding a letter to 'smile', but they represent different figure of speech. A simile is a figure of speech that compares two things using 'like' or 'as', while slime refers to a slippery, slimy substance and slide is a movement down a smooth surface. So, the correct answer is not 'smile' itself, but one of the other options provided.
