Read the excerpt from Roll of Thunder, Hear My Cry.

When we were alone, [Lillian Jean] confided her secrets to me: the boy she had passionately loved for the past year and the things she had done to attract his attention (with no success, I might add); the secrets of the girls she couldn't stand as well as those she could; and even a tidbit or two about her elder brothers' romantic adventures. All I had to do to prime the gossip pump was smile nicely and whisper a "Miz Lillian Jean" every now and then.

What motivates Lillian Jean to tell Cassie all her secrets?

A her feeling of superiority over Cassie
B her feeling that Cassie cannot be trusted
C her need to trick Cassie into liking her
D her need to make Cassie feel jealous
