As a river flows through a delta and reaches the sea, the velocity of water decreases, causing sediment to settle and accumulate in the delta region. This results in the total sediment load carried by the river decreasing as it approaches the sea. The maximum sediment grain size carried by the river may also decrease due to the settling of larger particles in the delta region. The discharge may not necessarily increase, as it depends on various factors such as the size and shape of the delta, tidal influences, and river flow rate. Therefore, option C is the best choice.
