Bank: River :: Coast : ?

Options

A. Flood
B. Waves
C. Sea
D. Beach

Explanation

To solve the analogy "Bank: River :: Coast : ?", we need to identify the relationship between the first pair of words and then apply that same relationship to the second pair.

### Step-by-Step Solution:

1. **Identify the relationship in the first pair (Bank: River)**:
- A "bank" is the land that borders a "river." It is the area of land that is adjacent to and often affected by the river.

2. **Apply the same relationship to the second pair (Coast: ?)**:
- Now we need to find a word that describes the land that borders a "coast."

3. **Consider the options**:
- Option 1: Flood - This does not relate to the land beside a coast.
- Option 2: Waves - Waves are a feature of the ocean but do not describe the land.
- Option 3: Sea - A sea is a body of water, not land.
- Option 4: Beach - A beach is the land that borders a sea or ocean, similar to how a bank borders a river.

4. **Determine the correct answer**:
- The correct answer is "Beach" because it is the land beside a sea, just as a bank is the land beside a river.

Thus, the answer to the analogy is:
**Coast : Beach**

### Final Answer:
**Coast : Beach**
