Final answer:
Biochemists and epidemiologists (Option D) are the professions most closely related to the field of genomics and molecular biology, as they involve working with genetic material and researching diseases at a molecular level.
Step-by-step explanation:
The set of jobs found in the field of genomics and molecular biology are most closely related to careers that directly handle genetic information and perform biological research at the molecular level. Individuals with a specialization in genomics might engage in sequencing an individual person's genome, which is a task related to bioinformatics. Such professionals are likely to have backgrounds in biology, microbiology, or similar fields.
A person with a master's degree in mycology or a Ph.D. might specialize in fungal genomics, molecular and cellular biology, or even biochemistry. An epidemiologist typically has a bachelor's degree and a master's degree in public health (MPH), and often they might be physicians or have a Ph.D. in biology or microbiology.
Therefore, from the provided options, biochemists and epidemiologists would be the most accurate examples of professionals working within the genomics and molecular biology sectors.
