Answer

To solve the question "Select the odd one out with respect to lifespan," we will analyze each statement provided in the question step by step.

### Step 1: Understand the concept of lifespan
Lifespan refers to the average length of life of an individual organism, which is the period between birth and natural death. Different species have different lifespans.

### Step 2: Analyze each statement

1. **Statement 1:** "Spans of organisms are not related with their size."
- This statement is correct. Lifespan is not necessarily correlated with the size of the organism. For example, larger animals do not always live longer than smaller ones.

2. **Statement 2:** "Crows and parrots show wide differences in their lifespan."
- This statement is also correct. Crows typically have an average lifespan of 10 to 15 years, while parrots can live for 50 to 70 years, showcasing a significant difference.

3. **Statement 3:** "Lifespan of rice is 3 to 4 weeks."
- This statement is incorrect. The lifespan of rice plants is generally around 3 to 7 months, not weeks.

4. **Statement 4:** "It is a period between birth and natural death of an organism."
- This statement is correct and describes the definition of lifespan accurately.

### Step 3: Identify the odd statement
From the analysis:
- Statements 1, 2, and 4 are correct.
- Statement 3 is incorrect regarding the lifespan of rice.

Thus, the odd one out is **Statement 3**: "Lifespan of rice is 3 to 4 weeks."

### Conclusion
The correct answer to the question is **Statement 3**.
