The correct answer is: simple harmonic and time period is independent of the density of the liquid.
Motion of an oscillating liquid column in a $\mathrm{U}$ tube is SHM with period, $T=2 \pi \sqrt{\frac{h}{g}}$, where $h$ is the height of liquid column in one arm of $U$ tube in equilibrium position of liquid. Therefore, $T$ is independent of density of liquid.
