Seeds can survive for thousands of years if they are
A
Cold and Dry
B
Cold and Wet
C
Warm and Dry
D
Warm and Wet
Explanation: 

Detailed explanation-1: -Dormancy allows seeds to survive for extended periods, which can aid in seed dispersal and spread out the growth and establishment of seedlings, increasing the likelihood that some of the next generations survive if conditions are not suitable for seedling establishment.

Detailed explanation-2: -Feat may help scientists preserve seeds for the future. The oldest plant ever to be regenerated has been grown from 32, 000-year-old seeds-beating the previous recordholder by some 30, 000 years. (Related: “’Methuselah’ Tree Grew From 2, 000-Year-Old Seed.")

Detailed explanation-3: -Seeds may be microbiotic (a lifespan of less than 3 years), mesobiotic (3 to 15 years), or macrobiotic (more than 15 years).

Detailed explanation-4: -Most seeds will germinate over quite a wide range of soil temperatures but the speed of germination will vary. Too cold and they’ll be very slow to sprout and too hot will also reduce the speed of germination. Far too cold or hot and they’ll just fail.
