Answer

To solve the question regarding "Minamata disease," we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Minamata Disease**:
- Minamata disease is a severe neurological disorder that was first identified in Minamata city, Japan, in 1956. It is primarily caused by mercury poisoning.

**Hint**: Remember that Minamata disease is linked to a specific location and a type of poisoning.

2. **Identifying the Cause**:
- The disease results from the consumption of fish contaminated with methylmercury, which is formed when mercury from industrial waste enters water bodies.

**Hint**: Focus on how mercury enters the food chain and affects human health.

3. **Sources of Mercury**:
- Mercury is released into the environment through industrial waste, particularly from factories that discharge effluents into rivers and oceans.

**Hint**: Consider the industrial processes that might contribute to mercury pollution.

4. **Effects of Methylmercury**:
- Methylmercury accumulates in fish, and when humans consume these fish, they can experience severe neurological symptoms such as ataxia, numbness, loss of vision, and hearing.

**Hint**: Think about the symptoms and how they relate to neurological function.

5. **Evaluating the Options**:
- Given the options:
a) Oil spills in sea
b) DDT pollution
c) Release of industrial waste containing mercury to water
d) Accumulation of arsenic
- The correct answer is option (c) "Release of industrial waste containing mercury to water," as it directly relates to the source of mercury that causes Minamata disease.

**Hint**: Eliminate options that do not relate to mercury or its effects.

### Final Answer:
The correct answer is **Release of industrial waste containing mercury to water**.
