Options

A. (i) only
B. (ii) and (iv) only
C. (i), (ii) and (iv) only
D. (ii), (iii) and (iv) only.

Explanation

To determine the uses of coal tar as a starting material for manufacturing, let's analyze the options provided in the question step by step.

### Step 1: Understand what coal tar is
Coal tar is a thick, black liquid that is produced through the destructive distillation of coal. This process involves heating coal in the absence of air, which breaks it down into various components, including coal tar.

### Step 2: Identify the components and uses of coal tar
Coal tar contains a variety of organic compounds, including aromatic hydrocarbons, phenols, and heterocyclic compounds. These components can be used in various industries.

### Step 3: Analyze each option provided in the question
1. **Drugs**: Coal tar is used in the pharmaceutical industry to produce certain medications, particularly those used to treat skin conditions (like psoriasis).

2. **Photographic materials**: Coal tar derivatives are used in the production of photographic materials, such as films and papers.

3. **Cookwares**: Coal tar is not typically used in the manufacturing of cookware. Cookware is generally made from metals or ceramics that can withstand high temperatures.

4. **Explosives**: Some compounds derived from coal tar can be used in the production of explosives.

### Step 4: Conclusion
Based on the analysis:
- Coal tar can be used for (i) Drugs, (ii) Photographic materials, and (iv) Explosives.
- Coal tar is not used for (iii) Cookwares.

### Final Answer:
Coal tar can be used as a starting material for manufacturing:
- (i) Drugs
- (ii) Photographic materials
- (iv) Explosives
