Answer 1

Answer:

See the answer below

Explanation:

It seems like you forgot to include the available options in order to answer the question.

However, according to plant pathologists, in order to establish that a particular organism is responsible for a certain observable disease, certain conditions have to be fulfilled. These conditions include:

• All plants showing the symptoms of the disease must have the organisms on their bodies.
• The organisms must be able to cause healthy plants to be diseased with the same symptoms as the original disease.
• Manually infected plants must show the presence of the organism

Any other condition that is short of the above-listed conditions can be considered to be least necessary in order for scientists to confirm if an organism is responsible for a particular disease.
