Answer:
The correct answer is "Ideal Type".
Step-by-step explanation:
In sociology, Ideal type refers to certain elements that are common to most of the cases when a certain social phenomenon occurs.
It does not refers to whats ideal or morally correct but what is usually common when a certain phenomenon happens such as the example of the r-ape.
The ideal type r-ape is perpetrated by armed complete strangers against unsuspecting females who are ambushed in darkness in blitz attacks.
Not all r-apes have those caractheristics, but certain elements of said example are fairly common in every r-ape.
In conclusion, the correct answer is "ideal type".
