Complete the passage using the suitable words given in option below.
A rough surface will offer a `underline((i))` frictional force than a smooth surface. The heavier the object, the `underline((ii))` will be the frictional force. Friction is a `underline((iii))` force.

Options

A. `{:((i),(ii),(iii)""),("Lower","Greater","Resistive"):}`
B. `{:((i),(ii),(iii)""),("Greater" ,"Lower" ,"Contact"):}`
C. `{:((i),(ii),(iii)""),("Greater" ,"Greater" ,"Contact"):}`
D. `{:((i),(ii),(iii)""),("Lower" ,"Lower" ,"Resistive"):}`

Explanation

To complete the passage, we will analyze each blank and fill them with the appropriate words based on the context of friction.

### Step-by-Step Solution:

1. **Blank (i)**: The passage states that "A rough surface will offer a `underline((i))` frictional force than a smooth surface."
- **Analysis**: Rough surfaces have more interlocking and greater resistance to motion compared to smooth surfaces.
- **Answer**: The correct word to fill in is **greater**.

2. **Blank (ii)**: The passage continues with "The heavier the object, the `underline((ii))` will be the frictional force."
- **Analysis**: Heavier objects exert more force due to their weight, which increases the frictional force acting on them.
- **Answer**: The correct word to fill in is **greater**.

3. **Blank (iii)**: Finally, the passage states "Friction is a `underline((iii))` force."
- **Analysis**: Friction occurs between two surfaces in contact and acts to oppose the relative motion between them. It is a force that arises from contact.
- **Answer**: The correct word to fill in is **contact**.

### Completed Passage:
A rough surface will offer a **greater** frictional force than a smooth surface. The heavier the object, the **greater** will be the frictional force. Friction is a **contact** force.
