Option 1: Black coffee as a hot beverage.

Black coffee is a liquid and when consumed, it enters the digestive system in the form of a hot beverage. The temperature of the liquid can affect its absorption rate. Generally, hot liquids are absorbed faster than cold liquids because heat increases blood flow, promoting faster absorption. Therefore, option 1 can be a potential contender for the fastest absorption.

Option 2: DDT taken as a poison.

DDT is a pesticide that is toxic to humans and animals. If ingested, it can harm the digestive system and interfere with absorption processes. Therefore, DDT is unlikely to be absorbed quickly through the walls of the digestive system.

Option 3: Raw alcohol taken as a drink.

Alcohol is known to be rapidly absorbed into the bloodstream through the walls of the digestive system. When consumed as a drink, alcohol bypasses certain digestion processes and is absorbed directly through the stomach and small intestine. This makes option 3 the correct answer as raw alcohol is absorbed the fastest among the given options.

Option 4: Ice cream as a dessert.

Ice cream is a solid food that undergoes digestion processes in the body. Solids generally take longer to be broken down and absorbed compared to liquids. Therefore, option 4
