Answer 1

The correct answer is C. Cellphones must not be banned in classrooms because they can be used as educational tools

Explanation:

A thesis statement is the main claim that guides an essay or a speech in which the writer or speaker aims at proving one point or position about one topic or situation by providing reasons and reliable evidence. Because of this strong thesis statements are statements that introduce a topic, explains the position of the author and provides some details of why the author believes this. This also implies thesis statements are not about reporting facts or just giving an opinion, these features make a thesis statement strong, debatable and specific.

Considering this, "Cellphones must not be banned in classrooms because they can be used as educational tools" is the statement that is debatable and specific because it introduces a specific topic which in this case is the use of cellphones in classroom, but it also provides the position of the author which is about not banning the use of these devices and a short explanation of why cellphones should not be banned which is that cellphones can be educational tools. As this is a strong position that might differ from others it requires evidence to be proved which make it debatable.
