ANSWER
The correct answer is d) GJ
EXPLANATION
A diameter is a line segment that connects two points on the circumference and passes through the centre.
From the above diagram, L is the centre of the circle.
The line segment HK and GJ connect two points on circumference and passes through the centre L.
This implies that, HK and GJ are diameters.
The correct answer is D.
Note that GK is NOT a diameter because it didn't pass through the centre.
It is called a chord.
