A. Bears	1. Diapause
B. Snail	2. Hibernation
C. Zooplanktons	3. Dormancy
D. Seeds	4. Aestivation

• A. A- 3, B- 4, C- 1, D- 2
• B. A- 2, B- 1, C- 4, D- 3
• C. A- 1, B- 4, C- 2, D- 1
• D. A- 2, B- 4, C- 1, D- 3

Answer 1

The correct option is D A- 2, B- 4, C- 1, D- 3

Hibernation is the state of an organism to conserve energy and the metabolic functions of the body slows down. During winters bears drop their body temperature and also their metabolic rate lowers down to 75%.

Snails remain in a an inactive stage during the hot summers. They hide themselves in the ground or under the vegetation to protect themselves from heat and dryness.

Many zooplanktons produce diapausing eggs when they switch from parthenogenesis to sexual reproduction.

Seeds become dormant and do not germinate under unfavourable conditions but start germinating on the arrival of favourable conditions such as water, light, temperature etc.

Thus, the correct answer is option D.
