A
Creeping & Tuberous
B
Taproot & Fibrous
C
Fibrous & Tuberous
D
Adventitious & Creeping
Explanation: 

Detailed explanation-1: -Taproots and fibrous roots are the two main types of root systems. In a taproot system, a main root grows vertically downward with a few lateral roots. Fibrous root systems arise at the base of the stem, where a cluster of roots forms a dense network that is shallower than a taproot.

Detailed explanation-2: -Napiform – This fleshy root is thick at the stem’s base and resembles a sphere. The taproot swells from the stem’s base and tapers suddenly. Example – Turnip. Fusiform – This type of taproot is tapered at both ends and is wider in the middle.

Detailed explanation-3: -The two types of root system are: Tap root system. Fibrous root system.

Detailed explanation-4: -There are two types of root systems: taproots and fibrous roots (also known as adventitious roots; Figure 2.1. 2). Tap roots have a prominent primary root that develops when the seed germinates and the radicle emerges. From there, secondary or lateral roots grow.

Detailed explanation-5: -So, the correct answer is ‘Radicle axis of the seed’.
