The correct answer is the theory of family resemblance. 
Wittgenstein was an Austrian-English philosopher who lectured at Cambridge University in the 1930s and 1940s. Wittgenstein was critical of the definition approach, and instead proposed the theory of family resemblance. According to the theory of family resemblance, words are not connected to other words and ideas by just one key feature, but rather through a various common features. Just like family members have resemblances and are similar to each other not through one trait, but through many traits, so are words.
