ii. In monocot the primary root is short lived.
iii. The root that arises from other part of the plant other than radicle is called adventitious root

Options

A. Two
B. Three
C. One
D. None of these

Answer

To determine how many statements are true, we will analyze each statement one by one.

### Step 1: Analyze Statement I
**Statement I:** The primary root and its branches constitute the tap root system.

**Explanation:**
The tap root system is characterized by a primary root (the main root) that develops from the radicle of the seed, along with its lateral branches (secondary roots). This statement is true.

### Step 2: Analyze Statement II
**Statement II:** In monocots, the primary root is short-lived.

**Explanation:**
In monocot plants, the primary root does not persist for long and is often replaced by a fibrous root system, which consists of numerous adventitious roots. This statement is also true.

### Step 3: Analyze Statement III
**Statement III:** The root that arises from other parts of the plant other than the radicle is called adventitious root.

**Explanation:**
Adventitious roots are indeed those that arise from parts of the plant other than the radicle, such as stems or leaves. This statement is true as well.

### Conclusion
Since all three statements are true, the answer is that all statements are correct.

### Final Answer
**All three statements are true.**
