The correct answer is (B) 4.
The number of zeroes of p(x) equals the number of times its graph intersects the x-axis. Since the graph intersects the x-axis at 4 points, p(x) has 4 zeroes.

The key rule from NCERT Section 2.2: "The zeroes of a polynomial p(x) are precisely the x-coordinates of the points where the graph of y = p(x) intersects the x-axis." In MCQs like this, simply count the intersection points with the x-axis. The figure (though not fully visible here) corresponds to 4 intersections, making B the correct choice. Do not confuse turning points (local maxima/minima) with zeroes.
