If a radius of a circle intersects a chord then it bisects the chord?
true of false

Totally false.  Just take your picture and either rotate the radius just a little,
or rotate the chord just a little.  The radius will still intersect the chord, but
it won't bisect it.

Could it be possible that you might possibly have mis-copied the question.

If you said that the radius intersects the chord and is perpendicular to it,
then the statement would be true.  Could that be the reason that the little
'corner' is marked in on the drawing ... to show that they're perpendicular ?
