d. All the above

Explanation: Histological methods are techniques used to prepare tissue samples for examination under a microscope.

a. Fixation and sectioning: This is the process of preserving biological tissues from decay due to autolysis or putrefaction. The tissue is then cut into thin sections for examination.

b. Staining: This is a technique used to enhance contrast in the microscopic image. Stains and dyes are frequently used in histology and in the medical fields of histopathology, hematology, and cytopathology that focus on the study and diagnoses of disease at a microscopic level.

c. Electron microscopy: This is a type of microscopy that uses a beam of electrons, instead of light, to create an image of the specimen. It is often used in histological studies to obtain high-resolution images of tissue structures.

Therefore, all the above are histological methods.
