Suppose the pth row has 3 shaded circles. The number of shaded circles in each row seems to be decreasing by 1 as we move down the rows. So, if the pth row has 3 shaded circles, then:
1. The (p-1)th row will have 3 + 1 = 4 shaded circles.
2. The (p+2)th row will have 3 - 2 = 1 shaded circle.
3. The (p-2)th row will have 3 + 2 = 5 shaded circles.
4. The (p+4)th row will have 3 - 4 = -1 shaded circle.
Since we can't have a negative number of shaded circles, the correct answer is:

2. The (p+2)th row will have 3 - 2 = 1 shaded circle.
3. The (p-2)th row will have 3 + 2 = 5 shaded circles.
4. The (p+4)th row will have 3 - 4 = -1 shaded circle.
Since we can't have a negative number of shaded circles, the correct answer is:
B. (p+2)th row will have 1 shaded circle.
