Assertion: Cattle feed should contain both roughage and concentrate.
Reason: Roughage of feed provides nutrients, while concentrate of food contains fibres

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the Reason is not the correct explanation of the assertion
C. If assertion is true but the Reason are false
D. If both Assertion and Reason are false

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that cattle feed should contain both roughage and concentrate. This is true because both components are essential for the health and digestion of cattle.

2. **Analyzing the Reason**:
- The reason provided claims that roughage of feed provides nutrients, while concentrate of food contains fibers. This statement is incorrect. Roughage primarily provides fiber, which aids in digestion, while concentrates are rich in nutrients such as proteins, fats, and vitamins.

3. **Evaluating the Relationship**:
- Since the assertion is true (cattle feed should indeed contain both roughage and concentrate), but the reason is false (roughage does not provide nutrients, it provides fiber), we can conclude that the assertion is correct while the reason is not.

4. **Choosing the Correct Option**:
- Based on the analysis, the correct option is that the assertion is true and the reason is false.

### Final Answer:
The correct answer is: The assertion is true but the reason is false.
