{'xerophyte': [0, 0, 1, 0], 'heliotrophytes': [0, 0, 1, 0], 'plants': [11, 0, 4, 4], 'tropophytes': [0, 0, 1, 0], 'virotophytes': [0, 0, 1, 0], 'saprophytes': [1, 0, 0, 0]}

The correct answer is option 3: Heliotrophytes.

To better understand the answer, let`s review each option:

1. Saprophytes: Saprophytes are plants that obtain their nutrients from dead and decaying organic matter. They do not have a specific adaptation to survive in different environments like xerophytes(hydrophytes in this case) do.

2. Tropophytes: Tropophytes are plants that can tolerate a wide range of environmental conditions and adapt to different climates. However, they do not specifically alternate between xerophytic and hydrophytic behaviors like the plants described in the question.

3. Heliotrophytes: Heliotrophytes are plants that exhibit different growth habits or characteristics in response to changes in light availability. This option is the correct answer as it describes plants that behave as xerophytes in one season and as hydrophytes in another season.

4. Virotophytes: This term seems to be a combination of "viro-" and "-phytes," but it does not correspond to any known plant adaptation or behavior. It is not a valid option.

Therefore, the correct answer is option 3: Heliotrophytes.
