The quality of heliotropism, a plant's ability to change its bearing to face the direction of the sun, is common in sunflowers. Moss displays the tendency to grow only on the side of trees opposite the most sunny direction. Therefore, moss exhibits the opposite phenomenon of heliotropism, which may be called contra-heliotropism.

The argument is flawed primarily because the author

A. does not take into consideration the fact that the direction of the sun changes during the day and between the southern and northern hemispheres
B. includes sunflowers and moss in the same group while ignoring obvious differences between them
C. creates a new word in Latin which does not really exist
D. fails to distinguish between a plant's special ability and a plant's special growth conditions
E. compares two types of plants which rarely grow in similar conditions
