Question

support mangrove trees out of the water
a. tap roots
b. prop roots
c. sand dunes
d. tide supports
please select the best answer from the choices provided

Explanation:

Mangrove trees have prop roots that grow out of the trunk and branches and help support the trees above the water level in the often - unstable and wet mangrove environment. Tap roots grow vertically downwards and are not relevant here. Sand dunes are landforms and not a part of the tree's support structure. There is no such thing as tide supports for mangrove trees in the biological sense.

Answer:

B. Prop roots
