Concept:Spelling errors often arise from incorrect vowel sequences, especially in common words like 'Achieved'.
Explanation:Review each option one by one.
Option A: 'Acheived' – the correct spelling is 'Achieved'. The vowels 'ie' are swapped to 'ei' incorrectly. The word means to successfully reach a goal.
Option B: 'Accessible' is spelled correctly (a-c-c-e-s-s-i-b-l-e).
Option C: 'Committee' has double m, double t, double e – correct.
Option D: 'Accommodate' has double c and double m – correct.
Therefore, only option A contains a misspelled word.
Answer:A. Acheived (the correct spelling is 'Achieved')
