In the Parable of the Sower (Matthew 13:1-23), what does the seed that falls on rocky ground primarily represent in terms of a person's initial reaction to the Word?

A Those who hear the word and immediately reject it due to persecution. B Those who hear the word and understand it deeply from the outset. C Those who hear the word and receive it with joy, but fall away when trouble or persecution comes. D Those who hear the word and are choked by worldly concerns and the deceitfulness of wealth.
