1. Days become cooler and shorter: As autumn arrives, the weather gradually becomes cooler. The days also become shorter, meaning there is less sunlight each day. This decrease in daylight hours is due to the Earth's tilt on its axis as it orbits the sun.

2. Animals prepare to survive the winter: Many animals start making preparations for the upcoming winter during autumn. They may begin to store food or find sheltered places to hibernate. For example, squirrels gather and store nuts, birds migrate to warmer regions, and bears build up fat reserves for hibernation.

3. Some trees begin to shed their leaves: One of the most notable changes during autumn is the colorful transformation of tree leaves. Some trees, such as deciduous trees, shed their leaves during this season. As the days shorten and temperatures drop, the trees receive less sunlight, which triggers the production of a pigment called anthocyanin. This pigment gives leaves their vibrant red, orange, and yellow colors before they eventually fall off.

4. Plants prepare to survive the winter: Just like animals, plants also make preparations to survive the harsh conditions of winter. They may enter a state of dormancy or store energy and nutrients in their roots to survive until spring. Some plants produce seeds or fruits during autumn, ensuring their offspring can grow when conditions become favorable again.

In summary, during autumn, days become cooler and shorter, animals prepare for winter, some trees shed their leaves, and plants make preparations to survive until spring. These changes are part of the natural cycle of life and adaptation to seasonal variations.Thus, all options are correct.
