• DOption D

  9% (5)

• D

Explanation

Option D correctly uses <area shape="circle" coords="x,y,r" ...>, where shape="circle" is the valid HTML attribute value and coords takes exactly three values: the center x-coordinate, center y-coordinate, and radius.

The other options are wrong for typical reasons seen in this type of question:

• Option A likely uses an incorrect shape value such as "round" or "circular" - neither is valid HTML; the only accepted values are circle, rect, and poly.
• Option B likely provides the wrong number of coords values (e.g., four values like a rectangle, which needs x1,y1,x2,y2).
• Option C likely confuses circle syntax with polygon syntax (shape="poly" requires an arbitrary list of x/y pairs).

Memory tip: Think "circle = center + radius = 3 numbers" - cx, cy, r. If you see four coordinates, that's a rectangle (x1,y1,x2,y2). Matching the coordinate count to the shape is the fastest way to eliminate wrong answers on the exam.
