Answer:
<em>The correct option is A) recasting</em>
Explanation:
Recasting can be described as a method for teaching a language in which the instructor corrects the learner by repeating the error back in a corrected format. In this way, the learner recognizes where he made a mistake and tends to understand it. 
Parents often use the technique of recasting to teach their children new complex words or to correct them if they speak any wrong word.
