Chapter 19 starts with a proposal from Mr. Collins to Elizabeth. How did she respond to his proposal?

Elizabeth very tactfully refused Mr. Collins' proposal.

“You are too hasty, sir,” she cried. “You forget that I have made no answer. Let me do it without further loss of time. Accept my thanks for the compliment you are paying me. I am very sensible of the honour of your proposals, but it is impossible for me to do otherwise than to decline them.”
