In `ul A` of the dicotyledonous plants , the `ul B` elongation of the radicle leads to the formation of `ul C`. Choose the correct option.

Options

A. `{:(A,B,C),("Few","Indirect","Rootlets"):}`
B. `{:(A,B,C),("Majority","Direct","Secondary roots"):}`
C. `{:(A,B,C),("Few","Indirect","Primary roots"):}`
D. `{:(A,B,C),("Majority","Direct","Primary roots"):}`

Answer

To solve the question, we need to fill in the blanks based on the information provided about dicotyledonous plants and the development of roots. Let's break it down step by step.

### Step-by-Step Solution:

1. **Identify the Plant Type**: The question specifies "dicotyledonous plants." These are plants that have two cotyledons (seed leaves) in their seeds.

2. **Understand the Role of the Radicle**: The radicle is the part of the plant embryo that develops into the primary root. In dicots, the radicle is crucial for establishing the root system.

3. **Elongation of the Radicle**: The question mentions the "elongation of the radicle." In dicotyledonous plants, this elongation is a direct process, meaning the radicle grows straight down into the soil.

4. **Formation of Roots**: As the radicle elongates, it leads to the formation of primary roots. These primary roots are the first roots that emerge from the seed and anchor the plant in the soil.

5. **Choose the Correct Option**: Based on the above reasoning, we can fill in the blanks:
- A: Majority (as most dicots exhibit this behavior)
- B: Direct (the growth of the radicle is a direct process)
- C: Primary roots (the result of the radicle's elongation)

Thus, the correct option is: **A - Majority, B - Direct, C - Primary roots.**

### Final Answer:
The correct option is: **A - Majority, B - Direct, C - Primary roots.**
