Answer and Explanation:
According to this theory, the young of a species may inherit certain physical characteristics which their parents acquired in the course of their daily lives. According to Lamarck, modern giraffes evolved from short-necked ancestors. The long necks develop as a result of stretching to reach the leaves of tall trees. The offspring of these giraffes inherited the long necks.
Lamarck's assumption of acquisition of characteristics by individuals in the course of their lifetimes is true. However, the passing of these traits to their offspring is not true. Acquired characteristics do not cause any alteration whatsoever in the hereditary information contained in the chromosomes. This theory is therefore not valid.

I think it’s most likely option B
The Douglas fir adapted to enable its survival in the taiga biome due to waxy needles.
<h3>What is Douglas fir?</h3>
Douglas fir may be defined as any type of a genus of tall evergreen timber trees of the pine family having stout bark, pitchy timber, and drooping cones with expanding branching.
Douglas-fir has elongate, narrow, and waxy needle-shaped leaves. The presence of waxy leaves precludes the thrashing of water through the process of transpiration and also controls freezing and leaves drying out.
The complete question is as follows:
How has the Douglas-fir adapted to enable its survival in the taiga biome?
- low growing
- perennial
- waxy needles
- survive on limited nutrients
Therefore, the correct option is C, i.e. waxy needles.
