A secant, is a line that intersects the circumference in two points.
For example OA is a radius (the distance that defines the circle) so we can conclude it does not cut the circumference in two points.

I think it will be (da)

anonymous · Answer

so it would be BC?

priyar · Answer

yes you are correct @exmac..good job!

hossamhoussien · Answer

@priyar @exmac I don't think BC is correct answer

anonymous · Answer

why is BC not correct?

hossamhoussien · Answer

because as @Owlcoffee told you "The secant is segment intersect the circle's circumference in two points "
BUT neither point B or C intersect the circumference 
I hope you get it

DA is not an answer option

priyar · Answer

@HossamHoussien i think u understood the def. wrongly... only the line has to intersect the circle the points need not lie on the circle...here B and C are just points that are marked to represent the line...Basically "SECANT IS A LINE THAT PASSES THROUGH THE CIRCLE INTERSECTING IT AT 2 POINTS" so BC is the correct answer..

priyar · Answer

Infact if the points where on the circle..it would be a Chord..here AD is a chord..

@priyar you're correct sorry for misunderstanding
