A ring buoy is dropped into the water at t=0 seconds. The buoy's height h relative to the water surface in feet is modeled by the quadratic function h(t)=2(2t−1)(2t−3). The graph of h(t) is given below, with the water surface at h=0. A function is graphed on a two quadrant coordinate plane. The horizontal t-axis goes from 0 to 2.5 in increments of 0.5 and the vertical h of t-axis goes from negative 3 to 7 in increments of 2. From left to right, a curve starts at (0, 6), falls at a decreasing rate, passing through (0.5, 0), reaches a minimum at (1, negative 2), rises, and ends at (1.5, 0). All points are plotted and labeled. All coordinates are approximate.

Which of the following statements is a correct description based on the graph of h(t)?

The buoy is on the water surface at t=6 seconds.

The buoy reaches its deepest point of 1 foot underwater at t=2 seconds.

The buoy hits the water surface at t=0.5 seconds.

The buoy is dropped from 1.5 feet above the water level.
