In the Parable of the Sower (Matthew 13:1-23), what does the seed that falls on rocky ground primarily represent concerning those who hear the word?

A Those who initially receive the word with joy but fall away when faced with hardship or persecution. B Those who hear the word but do not understand it, allowing the evil one to snatch it away. C Those who hear the word and accept it, bearing fruit in varying degrees. D Those who are preoccupied with worldly concerns and the deceitfulness of wealth, hindering the word's growth.
