Fill in the blanks by choosing an appropriate option .
A body sinks when its weight is ____(i)____ than the buoyant force acting on it . A body floats when its weight is ___(ii)___ than the buoyant force acting on it . A body sinks if the density of the body is __(iii)__ than the density of liquid . A body floats if the density of the body is __(iv)__ than the desity of liquid .

Options

A. `{:(,(i),(ii),(iii),(iv)),(,"More","Less","Less","More"):}`
B. `{:(,(i),(ii),(iii),(iv)),(,"More","Less","More","Less"):}`
C. `{:(,(i),(ii),(iii),(iv)),(,"Less","More","Less","More"):}`
D. `{:(,(i),(ii),(iii),(iv)),(,"Less","More","More","Less"):}`

Explanation

To solve the question, we need to fill in the blanks with appropriate terms based on the principles of buoyancy and density. Let's go through each blank step by step:

### Step-by-Step Solution

1. **Blank (i)**: A body sinks when its weight is **more** than the buoyant force acting on it.
- Explanation: When the weight of the object is greater than the buoyant force, the object will sink because the downward force (weight) exceeds the upward force (buoyant force).

2. **Blank (ii)**: A body floats when its weight is **less** than the buoyant force acting on it.
- Explanation: When the weight of the object is less than the buoyant force, the object will float because the upward force (buoyant force) is greater than the downward force (weight).

3. **Blank (iii)**: A body sinks if the density of the body is **more** than the density of the liquid.
- Explanation: If the density of the object is greater than the density of the liquid, it will sink because it displaces a volume of liquid that weighs less than the object itself.

4. **Blank (iv)**: A body floats if the density of the body is **less** than the density of the liquid.
- Explanation: If the density of the object is less than the density of the liquid, it will float because it displaces a volume of liquid that weighs more than the object.

### Final Answers
- (i) more
- (ii) less
- (iii) more
- (iv) less

### Summary of the Filled Blanks
A body sinks when its weight is **more** than the buoyant force acting on it. A body floats when its weight is **less** than the buoyant force acting on it. A body sinks if the density of the body is **more** than the density of the liquid. A body floats if the density of the body is **less** than the density of the liquid.
