The correct answer is A) Horizontal movement of the water toward the land after low tide. A flood current refers to the horizontal movement of water toward the land following low tide. This is because the rising tide causes the water level to increase, leading to a flow of water from the sea toward the shore. In contrast, the other answer choices describe either an ebb current (movement away from land after high tide) or the wrong direction of water movement in relation to the tidal cycle.
