Answer: the fallacy of composition
Step-by-step explanation:
The incorrect belief that what is true for the individual is also true for the group is known as the fallacy of composition.
The fallacy of composition occurs when one makes a general judgement for a group based on the fact that an individual in the group has a particular character or trait and hence, sane assumption is made for the group.
An example is saying Tom loves playing football, therefore all boys love playing football.
