A : A famous painting was painted by not using brush strokes in the usual manner, but rather a myriad of small colour dots. The colour you see it any given place on the painting, changes as you move away.
R : The angular separation of adjacent dots changes with the distance between them in the painting.

Options

A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true and R is not the correct explanation of A
C. A is true and R is false
D. Both A and R are false

Answer

To solve the question, we need to analyze the assertion (A) and the reason (R) given in the problem.

### Step 1: Understand the Assertion (A)
The assertion states that a famous painting was created using small color dots instead of traditional brush strokes. It further mentions that the color perceived at any point on the painting changes as one moves away from it.

**Hint:** Think about how colors blend together when viewed from different distances.

### Step 2: Analyze the Reason (R)
The reason provided states that the angular separation of adjacent dots changes with the distance between them in the painting. This implies that as you move further away, the dots appear closer together.

**Hint:** Consider how perspective affects the visibility of objects as distance increases.

### Step 3: Connect Assertion and Reason
Now, we need to connect the assertion and the reason. The assertion suggests that the color seen changes with distance due to the way the dots are arranged. The reason explains that as you move away, the angular separation between the dots decreases, making them indistinguishable and causing the colors to blend.

**Hint:** Reflect on how the blending of colors occurs when dots are viewed from a distance.

### Step 4: Determine the Truth of A and R
Both the assertion and the reason are true. The assertion accurately describes the phenomenon of color perception in pointillism (the technique used in the painting), and the reason correctly explains why this happens due to the change in angular separation.

**Hint:** Evaluate if both statements logically support each other.

### Step 5: Conclusion
Since both the assertion (A) and the reason (R) are true, and the reason provides a correct explanation for the assertion, we conclude that the answer is:

**Answer:** Both A and R are true, and R is the correct explanation of A.
