Options

A. comb is a good conductor
B. paper is a good conductor
C. the atoms is the paper get polarised by the charged comb
D. the comb possesses magnetic properties

Explanation

To solve the question, "A comb run through one's dry hair attracts small bits of paper. This is due to," we can break it down step by step:

### Step 1: Understand the Initial Condition
When a comb is run through dry hair, it undergoes a process that leads to charging. Initially, both the comb and the bits of paper are neutral.

**Hint:** Consider what happens to the comb when it interacts with hair.

### Step 2: Charging of the Comb
As the comb is rubbed against the dry hair, electrons are transferred from the hair to the comb. This process results in the comb becoming negatively charged, while the hair becomes positively charged.

**Hint:** Think about the nature of electric charge and how rubbing materials can transfer electrons.

### Step 3: Introducing the Neutral Paper
When the negatively charged comb is brought close to the neutral bits of paper, the electric field created by the charged comb affects the paper.

**Hint:** Recall how electric fields influence neutral objects.

### Step 4: Polarization of Paper
The electric field from the charged comb causes the atoms in the neutral paper to become polarized. This means that the electrons in the atoms of the paper are displaced slightly, causing one side of the atom to become more negative and the other side to become more positive.

**Hint:** Consider how charges interact with each other and how they can cause shifts in neutral materials.

### Step 5: Attraction of the Paper to the Comb
Due to the polarization, the side of the paper closest to the comb becomes positively charged (due to the displacement of electrons), while the opposite side remains neutral. The attraction occurs because opposite charges attract; thus, the negatively charged comb attracts the positively charged side of the paper.

**Hint:** Remember the principle that opposite charges attract while like charges repel.

### Conclusion
The attraction of small bits of paper to the comb is due to the polarization of the paper's atoms caused by the electric field from the charged comb. This results in an induced charge on the paper, leading to an attractive force.

**Final Answer:** The correct reason for the attraction is that the atoms of the paper are polarized by the charged comb.
