Which evidence would best support the student's claim?

• The cells of the leaf are too dark to be seen without the special lighting a microscope provides.

• The cells of the leaf are too small to be seen without the magnification a microscope provides.

• The cells of the leaf are too close together to be seen without using a microscope.

• The cells of the leaf are too far away to be seen without using a microscope.
