The extrinsic controlling system present in an organism is

Options

A. Hormonal control
B. Neutral control
C. Both (1) and (2)
D. Genetic control

Answer

To solve the question regarding the extrinsic controlling system present in an organism, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Extrinsic Controlling System":**
- The term "extrinsic" refers to factors or systems that originate outside of a particular organ or system within an organism. This means we are looking for controlling systems that influence the functioning of organs from an external perspective.

**Hint:** Think about what systems in the body send signals or control functions from outside the organ itself.

2. **Identify Examples of Extrinsic Control:**
- The two primary examples of extrinsic controlling systems in organisms are:
- **Hormonal Control:** This involves hormones released by glands in the endocrine system that travel through the bloodstream to target organs, influencing their function.
- **Neural Control:** This involves the nervous system, where nerve impulses are sent from the brain or spinal cord to various organs, controlling their activities.

**Hint:** Consider how the body communicates and regulates functions through hormones and nerve signals.

3. **Evaluate the Options Given:**
- The options provided in the question include:
- Hormonal control (Option 1)
- Neural control (Option 2)
- Both 1 and 2 (Option C)
- Genetic control (not considered extrinsic as it operates at a cellular level).

**Hint:** Look for the option that includes both examples mentioned.

4. **Select the Correct Answer:**
- Since both hormonal control and neural control are indeed extrinsic controlling systems, the correct answer is "both 1 and 2."

**Hint:** If you see options that combine two correct answers, that is often the right choice when both are valid.

### Final Answer:
The extrinsic controlling system present in an organism is **both hormonal control and neural control (Option C).**
