Match the functions in Column I with their properties in Column II.
\[
\begin{array}{ll}
\text{Column I} & \text{Column II}
\text{A) } |x| & \text{I. Strictly increasing and continuous in } (-1,1)
\text{B) } \sqrt{|x|} & \text{II. Continuous but not differentiable in } (-1,1)
\text{C) } x + |x| & \text{III. Differentiable in } (-1,1)
\text{D) } |x - |x|| + |x + 1| & \text{IV. Differentiable in } (-1,0), (0,1)
\end{array}
\]
