Final answer:
The most accurate symptom indicating meconium aspiration is C. Meconium stained fluids followed by tachypnea.
Step-by-step explanation:
Meconium aspiration is a condition where a newborn inhales meconium, which is the baby's first stool, during the delivery process. The most accurate symptom indicating meconium aspiration is C. Meconium stained fluids followed by tachypnea. Tachypnea refers to rapid breathing, and when the baby's respiratory distress is accompanied by meconium-stained fluids, it is a strong indication of meconium aspiration.
