To solve the question regarding the uses of Sorghum and Cotton, we will analyze each option step by step.

**Step 1: Understanding Sorghum**
- Sorghum, commonly known as Jowar, belongs to the family Poaceae.
- It is a rich source of protein (about 10%) and is also known for being a good source of B vitamins.
- One of the primary uses of sorghum is as animal feed, particularly in poultry.

**Step 2: Understanding Cotton**
- Cotton is a member of the Malvaceae family and is known for its soft, fluffy fibers.
- The primary use of cotton is in the paper industry, where its fibers are utilized.
- Additionally, cotton is used in cosmetics (for example, cotton pads for makeup removal) and medicinal purposes (such as in sanitary pads and wound cleaning).

**Step 3: Evaluating the Options**
- **Option (a)**: Blood purification and organic fertilizer.
- Incorrect, as neither sorghum nor cotton is used for blood purification or as organic fertilizer.

- **Option (b)**: Animal food and paper industry.
- Correct, since sorghum is used as animal feed and cotton is widely used in the paper industry.

- **Option (c)**: B vitamin and cosmetics.

- **Option (d)**: Explosives and organic fertilizer.
- Incorrect, as neither sorghum nor cotton is associated with explosives or organic fertilizer.

**Conclusion:**
The most accurate answer is **(b) Animal food and paper industry**, as it correctly identifies the primary uses of both sorghum and cotton.
