**Core Concept**
Controlled tipping is a method of waste disposal that involves the controlled placement of waste into a landfill, typically through a series of trenches or cells. This method aims to minimize environmental contamination and ensure the safe management of waste. Controlled tipping is often used for non-hazardous waste, such as municipal solid waste.

**Why the Correct Answer is Right**
Controlled tipping involves the careful placement of waste into a landfill, which helps to prevent leachate and gas production. The waste is typically compacted and covered regularly to minimize odors and pest attraction. This method is often preferred for its cost-effectiveness and ease of implementation. The controlled tipping process also allows for the monitoring of gas and leachate production, enabling prompt action to be taken in case of any contamination.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to the question, as it does not describe a method of waste disposal.
**Option B:** This option may refer to a different method of waste disposal, such as incineration, which involves the burning of waste at high temperatures.
**Option C:** This option may refer to a different method of waste disposal, such as sanitary landfilling, which involves the careful placement of waste into a landfill with a liner and leachate collection system.

**Clinical Pearl / High-Yield Fact**
Controlled tipping is often used for non-hazardous waste, such as municipal solid waste, but it is not suitable for hazardous waste, which requires specialized disposal methods.

**Correct Answer: C. Controlled tipping is a method of disposal of municipal solid waste.**
