B
Phototropism

C
Geotropism

D
Both B and C

Solution

The correct option is A Both B and C
Cholodny-Went's theory is based on the unequal distribution of plant hormone auxin. It proposes that auxin hormone is synthesized in the coleoptile tip. It moves down the coleoptile. Hence, the tip has a higher concentration of auxin that causes the coleoptile to bend towards the light source and lower regions have an auxin asymmetry. This results in differential growth in geotropism. 
Thus, the correct answer is option D.
