Given below are two statements, one is labelled as Assertion A and other is labelled as Reason R
Assertion A: Butylated hydroxy anisole when added to butter increases its shelf life.
Reason R: Butylated hydroxy anisole is more reactive towards oxygen than food.
In the light of the above statements, choose the most appropriate answer from the options given below

Options

A. `A ` is correct but `R ` is not correct
B. Both `A` and `R` are correct but `R` is NOT the correct explanation of `A`
C. `A` is not correct but `R` is correct
D. Both`A` and `R` are correct but `R` is the correct explanation of `A`

Answer

To solve the question, we need to analyze both the Assertion (A) and the Reason (R) provided.

### Step 1: Analyze Assertion A
**Assertion A:** Butylated hydroxy anisole when added to butter increases its shelf life.

- Butylated hydroxy anisole (BHA) is a well-known antioxidant used in food preservation. It helps to prevent the oxidation of fats and oils, which can lead to rancidity. Therefore, the assertion that BHA increases the shelf life of butter is correct.

### Step 2: Analyze Reason R
**Reason R:** Butylated hydroxy anisole is more reactive towards oxygen than food.

- The statement indicates that BHA reacts with oxygen more readily than the food itself. This is true because antioxidants like BHA are designed to react with oxygen to prevent oxidative damage to the food. Hence, this reason is also correct.

### Step 3: Determine the relationship between A and R
- Since both statements A and R are correct, we need to determine if R explains A. The reason provided (R) does explain why the assertion (A) is true. BHA increases the shelf life of butter because it reacts with oxygen before the food does, thereby preventing spoilage.

### Conclusion
Both Assertion A and Reason R are correct, and R is the correct explanation of A.

### Final Answer
- Both A and R are correct, and R is the correct explanation of A.
