Identify the statements as true (T) or false (F) w.r.t secondary growth in root and choose the correct option.
I. Vascular cambium is partially secondary in origin.
II. Vascular cambium is formed as continuous and complete but wavy ring.
III. Cork cambium arises from cortical cells.

Options

A. `{:(I,II,III),(T,F,F):}`
B. `{:(I,II,III),(F,T,T):}`
C. `{:(I,II,III),(T,T,F):}`
D. `{:(I,II,III),(F,T,F):}`

Answer

To solve the question, we need to evaluate each statement regarding secondary growth in roots and determine whether they are true (T) or false (F).

### Step-by-Step Solution:

1. **Evaluate Statement I: "Vascular cambium is partially secondary in origin."**
- The vascular cambium in roots is primarily formed during secondary growth. It is not partially secondary; it is completely secondary in origin. Therefore, this statement is **False (F)**.

2. **Evaluate Statement II: "Vascular cambium is formed as continuous and complete but wavy ring."**
- The vascular cambium does indeed form a continuous and complete ring in roots, although it may appear wavy due to the nature of growth. Hence, this statement is **True (T)**.

3. **Evaluate Statement III: "Cork cambium arises from cortical cells."**
- Cork cambium does not arise from cortical cells; rather, it arises from the pericycle, which is located just inside the endodermis. Therefore, this statement is **False (F)**.

### Summary of Statements:
- I: False (F)
- II: True (T)
- III: False (F)

### Correct Option:
Based on the evaluations, the correct option that reflects these truths and falsehoods would be the one that corresponds to the findings: I (F), II (T), III (F).
