Question:

<p>Max \{|PQ|\} is</p>
<p>(a) 1</p>
<p>(b) 4</p>
<p>(c) 0</p>
<p>(d) 2</p>

Step-by-Step Solution

Key Concept: The maximum distance between two constrained points is found by optimizing their positions given the constraints.
The maximum distance between P (on the circle) and Q (inside the circle with integer abscissa) is 2, determined by the geometric constraints of their positions.
Correct Answer: d
