The Parable of the Sower (Matthew 13, Mark 4, Luke 8) describes seeds falling on different types of ground. What does the seed that falls on rocky ground represent?

A Those who hear the word and immediately receive it with joy, but have no root and endure only for a while. B Those who hear the word, but worldly anxieties and the lure of wealth choke it, making it unfruitful. C Those who hear the word and understand it, and consequently bear fruit. D Those who hear the word, but do not understand it, and the evil one snatches away what was sown in their heart.
