Answer 1

Answer: D If a base word has only one syllable and ends in one consonant, double the final consonant.

Explanation:

You must double those final consonants that you have in your word before a suffix which means first, double the final consonant and then add it.

• For example, it can be, stop-stopped(stop + p + ed), bag-bagged, drop-dropped, fog-foggy, run-running. It is used when some of the words are ending with the consonants.

Suffixes that you add, in this case, should be vowel suffixes which are ED and ING.
