The solution of the above question will be similar to this. The only contradiction is that the chords are used in place of tangents. Hope you understand.

Answer:d
Step-by-step explanation:
Just draw another tangent AD.
Now consider tangents AD & DC.
Since lenghts of tangents from an external point to a circle is equal,
AD = CD ---------[1]
Similarly, AD = AB ---------[2] ( with the same reason) .
Now from [1] & [2]
AB = CD
Hence proved.
