Which conclusion is best supported by the reasoning in this passage from Patrick Henry's speech?
Shall we try argument? Sir, we have been trying that for the last
ten years. Have we anything new to offer on the subject?
Nothing. We have held the subject up in every light of which it is
capable, but it has been all in vain. Shall we resort to entreaty and
humble supplication? What terms shall we find, which have not
been already exhausted?
A. We should continue trying to find a peaceful solution to the issue.
B. The idea is useless we've tried everything but nothing has worked
C. It's no use waiting any longer the time to actis now
D. We should look for new ways to argue our point against our enemy

It’s no use waiting any longer; the time to act is now.
