Question:medium

A seed technologist placed a set of 100 seeds for a germination test. After 8 days, she found that 70 seeds germinated and 30 seeds did not. The most probable reasons for the no germination of these 30 seeds are -
(A) The seeds were not viable at all
(B) The seed coat was impermeable
(C) The seed coat was permeable but the seeds were dead
(D) The seeds were viable but the conditions for the germination were not favorable
Choose the correct answer from the options given below :

Show Hint

Remember that a standard laboratory seed germination test is defined by maintaining 100% optimal/favorable conditions. Therefore, you can immediately eliminate "unfavorable conditions" (D) as a valid reason for failure within the test, which quickly guides you to the correct option.
