In monocot roots which types of vascular bundles are found?

Read the following statements about the vascular bundles:
(a) In roots, xylem and phloem in a vascular bundle are arranged in an alternate manner along the different radii.
(b) Conjoint closed vascular bundles do not possess cambium.
(c) In open vascular bundles, cambium is present in between xylem and phloem.
(d) The vascular bundles of dicotyledonous stem possess endarch protoxylem.
(e) In monocotyledonous root, usually there are more than six xylem bundles present.

Choose the correct answer from the options given below :

A layer of root, that adjusts the quantity and types of solutes that reach the xylem is

The given figure shows T.S. of:

A transverse section of a typical monocot root shows

(a) Barrel-shaped endodermal cells with casparian strips.

(b) Diarch to hexarch vascular bundles.

(c) Protoxylem towards center

 and metaxylem towards periphery.

(d) Large well-developed parenchymatous pith in center.

Arrange the following structure based on their location from periphery to centre with respect to the anatomy of a dicotyledon root.

I. Pericycle
II. Casparian strips
III. Epiblema
IV. Conjunctive tissue
