Given data:

The given radius is JK=JM=3.

The given length is LM=2.

The tangent is always perpendicular to the radius, the expression for the Pythagoras theorem is,


\begin{gathered} (JK)^2+(KL)^2=(JL)^2 \\ (JK)^2+(KL)^2=(JM++ML)^2 \end{gathered}

Substitute the given values in the above expression.


\begin{gathered} (3)^2+(KL)^2=(3+2)^2 \\ 9+(KL)^2=25 \\ (KL)^2=16 \\ KL=4 \end{gathered}

Thus, the first option is correct.
