    Answer : Option A

    Explanation :

    Ria coasts are known as coastlines of submergence. A ria coast is a coastline having several parallel rias separated by prominent ridges, extending a distance inland. The sea level change that caused the submergence of a river valley may be either eustatic (where global sea levels rise), or isostatic(where the local land sinks).
