\begin{align} \int\left(\sqrt x + \frac {1}{\sqrt x}\right).dx \end{align}
\begin{align}= \int x^\frac{1}{2}.dx + \int x^\frac{-1}{2}.dx \end{align}
\begin{align}= \left(\frac {x^\frac{3}{2}}{\frac{3}{2}}\right) + \left(\frac {x^\frac{1}{2}}{\frac{1}{2}}\right) + C\end{align}
\begin{align}= \frac {2}{3} . x^{\frac{3}{2}}+ 2x^\frac{1}{2} + C\end{align}
Hence, the Correct Answer is C.
