B. (A), (C) and (D)
C. (C) and (D)
D. (B) and (C).

Answer 1

In the given question all statements talk about the roots of the plant and their structure in different plant species. Roots are the underground part of the plant which extract nutrients from the soil and provide nutrients to the plant and also provide support. Roots are of mainly two types such as taproot and adventitious root system.

Complete answer:
As the root majorly is of two types such as taproot which have a long main stem and which bear secondary and tertiary roots on it while in adventitious root their no main branch is present instead of number branching occurring on roots.
A. Root is divided into three regions such as the maturation region where root hair is present and no active division takes place but elongation is the second region of the root which has actively dividing cells and third is root cap which penetrates the soil.
B. Pneumatophores are the minute opening present on the root, which exchange gases and these types of opening called pneumatophores are present in plant Rhizophora in which it shows negative geotropism.
C. Adventitious roots are present in the banyan tree, which arises from the branches of the banyan tree that are called prop roots, which elongate and attach to the ground and provide support to the plant body.
D. Maize and sugarcane do not bear prop root, instead, they bear root from its lower nodes.
Hence, the correct option is D.

Note: Roots arise from the radicle of the seed, the root is present below the ground which holds the soil particle around and gets nutrient and water to make available for the plant, roots are the house of several microbes such as bacteria, fungi, and algae that help the plant growth.
