B. (ii) and (iii)
C. (i) ,(ii) and (iii)
D. All

Answer

To determine which statements regarding electric charge are correct, let's analyze each statement step by step.

### Step 1: Analyze Statement (i)
**Statement (i):** If a body is having positive charge i.e. shortage of electrons.

- A positive charge indicates that there are fewer electrons than protons in the body. This occurs when electrons are removed from the body, leading to a net positive charge. Therefore, this statement is **correct**.

### Step 2: Analyze Statement (ii)
**Statement (ii):** If a body is having negative charge i.e. excess of electrons.

- A negative charge indicates that there are more electrons than protons in the body. This occurs when extra electrons are added to the body, resulting in a net negative charge. Thus, this statement is **correct**.

### Step 3: Analyze Statement (iii)
**Statement (iii):** Minimum possible charge = ±1.6 x 10^(-19) C.

- The charge of a single electron (or proton) is approximately 1.6 x 10^(-19) C. This is the smallest unit of charge that can exist independently in nature. Therefore, this statement is **correct**.

### Step 4: Analyze Statement (iv)
**Statement (iv):** Charge is quantized i.e. Q = ±n e, where n = 1, 2, 3, 4, ...

- Charge is indeed quantized, meaning it can only exist in discrete amounts that are integer multiples of the elementary charge (e). This means that any charge Q can be expressed as Q = ±n e, where n is a whole number. Therefore, this statement is **correct**.

### Conclusion
All four statements regarding electric charge are correct.

### Final Answer
All statements (i), (ii), (iii), and (iv) are correct regarding electric charge.
