Hint: Taproot, the main root of the primary root chain, which develops downwards vertically. Most dicotyledonous plants (see cotyledon) grow taproots, such as dandelions, and others are adapted for food storage, such as the edible roots of carrots and beets.
Complete answer:
At germination, the root of the embryonic radicle is the first structure to grow from most plants. A taproot is the primary root. Smaller lateral roots (secondary roots) usually originate from the taproot in plants in which the taproot remains and may in turn grow even smaller lateral roots (tertiary roots).
This helps to maximise the surface area for the absorption of water and minerals. The initial taproot is easily transformed in other plants into a fibrous, or diffuse, system in which the initial secondary roots soon equal or surpass the primary root in size and no single taproot is well established. Generally, fibrous root systems are shallower than taproot systems.
The deep feeder and surface feeder are two types of tap root system. There is an elongated taproot in the Deep Feeder tap root system that penetrates the deeper layers of the soil. It is found mainly in trees. The racemose tap root system is also called the deep feeder tap root system.
The tap root does not elongate greatly in surface feeders. The secondary roots, often horizontal near the soil surface, spread to a larger degree. Such a mechanism is also known as the root system of the cymose tap. Thin fibrous roots form the cymose or surface feeder tap root system of certain annual plants. It can be called the root system of a fibrous tap.
Example : Balsam, Mango.
Hence, the correct answer is option (A)
Note: A taproot's benefits include the fact that they penetrate deep into the soil and thus can find deep underground water and minerals, for example, the mesquite plant has roots that can penetrate in search of water up to 150 ft. deep. It is therefore very tolerant of drought.
In windy conditions, the taproot is also excellent at anchoring the plant into the soil to keep it from being blown over.
