Within the Parable of the Sower (Matthew 13, Mark 4, Luke 8), what does the seed that falls on 'good soil' represent?

A Those who initially embrace the word with enthusiasm but later fall away due to persecution. B Those who hear the word, but worldly anxieties and the deceitfulness of wealth choke it. C Those who hear the word and understand it, bearing fruit and producing a harvest. D Those who hear the word, but it is immediately snatched away by the evil one.
