Answer:
Letter <u>A</u> indicates the <u>epidermis</u>, which is the outer layer of the root.
Explanation:
The internal structure of the eudicot root consists of <em>three concentrical layers</em>: The <u>epidermis</u><u>,</u> the cortex, and the central vascular cylinder.
The epidermis is the outer layer of the root. It <em>covers the totality of the root surface</em>, <em>absorbs water</em> and <em>minerals from the soil,</em> and <em>protects the internal tissues</em>.
The <em>cortex</em> occupies a big part of the root and its <em>located under the epidermis</em>. The <em>most internal cell layer</em> of the cortex is called <em>endodermis</em>.
The <em>vascular cylinder</em> is composed of <em>vascular tissues</em> -the xylem and the phloem- that is <em>surrounded by</em> one or more cell layers called <em>pericycle</em>. The xylem looks like a <em>cross of big cells</em> in the center, and the phloem occupies the spaces between the pericycle and the xylem.
