Answer 2

The one that needs to double the final consonant before adding the suffix is the first one: Omitted.

Step-by-step explanation:

The word omit, when adding the suffix ed, has to double its final consonant because the suffix starts with a vowel. This grammar rule is known as the Doubling Rule: in order to know how to write a word adding a suffix, you have to check if it has a One, One, One (one syllable ending in one consonant after one vowel). Then, you have to look at the ending: Does it start with a vowel? If the answer to these two questions is yes, then you have to double the last letter in the base word.
