Verified step by step guidance

1. Understand the concept of phenotypic plasticity: Phenotypic plasticity refers to the ability of an organism to change its phenotype in response to environmental conditions.
2. Identify the key characteristic of phenotypic plasticity: It involves changes that are not genetically predetermined but are influenced by external factors.
3. Analyze each statement: Determine whether the trait described can change due to environmental factors.
4. Evaluate the statement about the plant: Consider how increased sunlight can lead to a change in the plant's growth, demonstrating phenotypic plasticity.
5. Conclude which statement best fits the definition: Recognize that the plant growing taller in response to increased sunlight is an example of phenotypic plasticity.
