The 'Standard of Care' generally used in case of tort of negligence is :

The standard of care in negligence is objective: the defendant must show the care that a reasonable man would exercise in the circumstances, as stated in Blyth v. Birmingham Waterworks Co. (1856), which is "The skill and foresight of an average person of prudence". It is neither "The skill and care of a qualified person" nor "The skill and care of an intelligent person" nor simply "The skill and foresight of an adult person"; only where a person professes special skill is the standard raised to that of a reasonably competent member of that profession.
