Which sentence correctly uses a contraction to show missing letters?

• A. It's important to review your work.
• B. It is important to review your work.
• C. It would be important to review your work.
• D. I am important to review your work.

Answer: (A)

Using contractions to show missing letters means replacing part of a word with an apostrophe. In the sentence "It's important to review your work," the word "It's" is a contraction for "It is." The apostrophe stands in for the letters "is," so the sentence reads as if it had the full form but still conveys the same meaning: It is important to review your work. The other lines don’t use a contraction. They spell out "It is," "It would be," or "I am," which don’t demonstrate a missing-letter contraction.
