Answer:
D). School uniforms should not be required because they reduce individual expression.
Step-by-step explanation:
A claim is described as statement which assumes something to be the truth and yet to be verified and proved to be true. A claim is characterized as effective when it asserts a specific idea clearly and completely and is logically supported by sufficient facts or evidences.
As per the question, option D demonstrates an effective claim(' i.e. 'School uniforms should not be required') most likely as it offers a complete thought which is assumed to be true and is appropriately supported by reason/logic that 'they reduce individual expression' which can be argued or verified. Thus, option D is the correct answer.
