Answer the following questions by selecting the most appropriate option
'Recognition of patterns and their completion' is an essential part of Mathematics curriculum at primary stage as it

Options

A. develops creativity and artisitic attributes in students
B. prepares students to take up competitive examinations
C. helps the students in solving 'Sudoku' puzzles
D. promotes creavtivity amongst students and helps them to understand properties of numbers and operations

Answer

To solve the question, we need to analyze the options provided and determine which one best describes the importance of recognizing patterns and their completion in the mathematics curriculum at the primary stage.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks why the recognition of patterns and their completion is essential in the primary mathematics curriculum.

2. **Evaluate Option A**:
- Option A states that it "may develop creativity and artistic attributes in students."
- While recognizing patterns can foster creativity, this option focuses more on artistic attributes, which may not be directly related to mathematics.

3. **Evaluate Option B**:
- Option B suggests that it "may help prepare students to take a competitive examination."
- Although pattern recognition can aid in problem-solving, this option is more about exam preparation rather than the intrinsic value of understanding patterns in mathematics.

4. **Evaluate Option C**:
- Option C claims that it "helps the student in solving Sudoku puzzles."
- While Sudoku does involve pattern recognition, this option is too narrow and specific to be the main reason for including pattern recognition in the curriculum.

5. **Evaluate Option D**:
- Option D states that it "promotes creativity among students and helps them to understand properties of numbers and operations."
- This option encompasses both the creative aspect and the mathematical understanding that comes from recognizing patterns, making it a comprehensive choice.

6. **Select the Best Option**:
- After evaluating all options, Option D is the most appropriate answer as it highlights the dual benefits of creativity and understanding mathematical concepts.

### Final Answer:
The correct answer is **Option D: promotes creativity among students and helps them to understand properties of numbers and operations.**
