The correct solution involves the principles of kinematics, specifically the equation for displacement under constant acceleration (gravity, in this case). The term $Lg t^2$ suggests a quadratic relationship with time, which is characteristic of motion under gravity. The subtraction inside the square root ($L^2 - Lgt^2$) correctly accounts for the decreasing displacement from the initial position $L$ as time increases, consistent with the expected physical behavior.
