Which of the following finding is diagnostic of antemoem drowning -

Reff: The synopsis of forensic medicine& Toxicology 28th edition pg: 194 Water is present in the stomach and duodenum. Much amount of water may be swallowed which passes in to the duodenum. It does not enter into the stomach after death as a result of the hydrostatic pressure. If a body is kept at a depth of 15 meters for 65 hours then no water enters the stomach. So it is very vital sign that the person entered the water when he was alive and no significant sign of drowning. The fallacy is that the deceased might have drank water prior to death or taken beverages before drowning in water. So it can considered as a sign of antemoem drowning.
