D. temperature must be above 80 degrees
E. temperature must be below 80 degrees
The answer is A
Explanation:
Germination is practically the very first step of every seed-producing plant. It is the process whereby seeds sprout or begin to grow. Germination requires certain conditions to be met in order to occur. This conditions include presence of moisture in the soil etc.
The water is absorbed by the seed helps to soften the seed coat, which protects the seed from damage. The seed coat ruptures, causing the emergence of growth structures from the seed. In general, seeds need water to activate their dormant physiology. Hence, the moisture content of the seed must not be lower than 9%.

Acquired immunity is the type of immunity that exists when a person is exposed to an antigen and subsequently makes antibodies against the antigen.
Immunity is the defense mechanism of the nervous system to avoid pathogens affecting the body and making it sick. There are two major types of immunity: innate and acquired. Innate immunity is the kind of immunity present in the human body by birth. Whereas, acquired immunity is gained over time.
Acquired immunity specifically promotes the antibodies or lymphocytes to inhibit the action of pathogens when it encounters one. It is further categorized into two types: active and passive immunity.
Active immunity indulges in the primary response to a pathogen. It produces antibodies to fight against it and preserves some to fight against the same pathogen encountered for the second time. Passive immunity, in addition, involves the medications prescribed to enhance immunity.
