Which term describes a prolonged period of dormancy, typically during winter?

• A. Hibernate
• B. Undulation
• C. Concertina
• D. Ambush

Answer: (A)

A seasonally induced energy-saving state during which an animal greatly slows activity for an extended period is described by the verb to hibernate. When animals hibernate, their metabolism drops dramatically, body temperature falls, and breathing and heart rate slow, allowing them to survive winter with little food. This behavior is the action of entering that deep dormancy, while the noun form hibernation describes the period itself. The other terms don’t fit because they refer to movements or strategies (undulation is wave-like movement, concertina a folding or crawling action, ambush a hunting tactic) rather than winter dormancy.
