In the Parable of the Sower (Matthew 13:1-23), what does the thorny ground represent in the context of receiving the word of God?

A Those who initially accept the word with joy, but later fall away due to persecution. B Those who hear the word but do not understand it. C Those who hear the word, but the worries of this life and the deceitfulness of wealth choke it, making it unfruitful. D Those who hear the word and produce a harvest, yielding a hundred, sixty or thirty times what was sown.
