a)increasing the amount of light that shines on the crystal
b)decreasing the amount of light that shines on the crystal
c)increasing the strength of the objective lens
d)decreasing the strength of the objective lens

The correct answer is "increasing the strength of the objective lens".

Explanation:

Microscope: It is an optical instrument which is used for viewing the enlarged images of the small objects. Microscope consists of combination of lenses.

To see the enlarge image of the object, one has to increase the strength of the objective lens of a microscope. It helps to change the magnification of the specimen. It helps to alter the power of a lens from high power to low power or vice versa.

In the given problem, Samantha is observing a salt crystal under a microscope. She wants to view more details by enlarging the image of the crystal. She has to increase the strength of the objective lens of microscope.
