• B. Which cannot resist the change in temperature and pressure.
• C. They have long viability.

Answer 1

The correct option is B Which cannot resist the change in temperature and pressure.

Orthodox seeds are seeds which will survive drying or freezing during ex-situ conservation. There is variation in the ability of orthodox seeds to withstand drying and storage with some seeds being more sensitive than others. Thus, some seeds are considered intermediate in their storage capability while others are fully orthodox.
Thus, the correct answer is option B.
