In which of the following case the doctrine of 'Duty of Care' has been explained.

Donoghue vs Stevenson

The correct answer is Option (1) → Donoghue vs Stevenson

This landmark case, decided in 1932, established the modern law of negligence and introduced the concept of a "duty of care." In this case, Mrs. Donoghue became ill after drinking a ginger beer that contained a dead snail, and she sued the manufacturer, Mr. Stevenson. The court held that the manufacturer owed a duty of care to the consumer, even though there was no direct contract between them, thus laying the foundation for the principle of negligence.

The other cases listed do not primarily focus on the doctrine of 'Duty of Care':

• M.C. Mehta vs U.O.I deals with environmental law and public interest litigation.
• Reyland vs Fletcher involves the concept of strict liability in tort law.
• Maneka Gandhi vs U.O.I is a significant case regarding personal liberty and the right to life under Article 21 of the Indian Constitution.
