Question

in a suspected drowning case, which post-mortem sign is commonly observed: rigor mortis present in the fingers only; fluid in the airways and nostrils; absence of water in the lungs; deep gashes on the lower legs

Explanation:

In drowning cases, fluid (water) entering the airways and nostrils is a common post - mortem sign. Rigor mortis in fingers only is not typical for drowning. Drowning usually involves water in lungs, so absence is wrong. Deep gashes on legs are not related to drowning.

Answer:

B. Fluid in the airways and nostrils
