The correct answers are A. Begin and B. Shop
Explanation:
Suffixes are syllables or letters added after a word to create a new word derived from the original word. Additionally, in some cases due to language conventions, the original word is modified before any suffix can be added; this includes doubling the final consonant. From the options, this occurs in the words begin and shop; for example, in the word "beginner", in which the prefix "-er" is added to form a noun, the last letter "n" is doubled; this also applies to the word beginning. Similarly, in words such as "shopper" with the -er suffix or "shopping" the "p" is doubled.
