Ascientist receives a seed sample from a plant growing in an unknown location and discovers that prolonged cold treatment is needed to break seed dormancy. this suggests that in the native habitat of the plant, the colder part of the year
a. occurs right before the best growing season

b. is favorable for growth

c. lasts for several months

d. is brief

e. none of the above.

a.  occurs right before the best growing season

Explanation:

Seed dormancy prevents seeds from germinating in unsuitable conditions such as competing for light and water with other plants or being able to be eaten from a high population of herbivores species during certain seasons.

If a dormant seed is broken after prolonged cold treatment, then this cold part of the year occurs right before the best growing season for this dormant seed. The native habitat of the plant must have an undetermined and cold season that breaks seed dormancy.
